1983–1984: Formation and first album in
Philadelphia in November 1985 Kiedis began working with Flea and drummer
Jack Irons, where he was described as a "manic
master of ceremonies" before he even began singing for the group. Irons and Slovak began playing together in a high school band called Chain Reaction. The group included then bassist Tom Strasman and
Chile-born vocalist and guitarist
Alain Johannes. Strasman was intent on becoming a lawyer, and quit the band to focus on college. Flea soon offered Kiedis a position in the band. Kiedis began as a
hype man, going out in front of the band and getting the audience pumped up. Kiedis, Slovak, and Flea began to create their own music after finding inspiration in a punk-
funk fusion band called
Defunkt. Kiedis rejected the violence and
misogyny of the Los Angeles punk rock scene, and wanted to create a more peaceful environment to encourage women to come to concerts. The three reunited with Irons, who had recently left his previous band Anthym, to form a new band called Tony Flow and the Miraculously Majestic Masters of Mayhem. The band had only one song, titled "Out in L.A.", and was formed for the purpose of playing the song once. The song was based on a guitar riff that Slovak wrote while jamming with Irons, and was not meant to become a real song until Kiedis decided to
rap over the music. Mike Chester, a friend of Kiedis', invited the band to open for his act Mike and Neighbor's Voices at The Rhythm Lounge, as he felt that Kiedis had potential as a frontman. Slovak and Flea felt that Kiedis did not have enough vocal experience, but the two eventually agreed to perform. After the group's first show at The Rhythm Lounge, the owner of the bar asked them to return, but with two songs instead of one. After several more shows, and the addition of several songs to their repertoire, the band's name was changed to The Red Hot Chili Peppers. The band's concert repertoire grew to ten songs as a result of months of playing at local nightclubs and bars. At a performance at a
strip club in Hollywood called Kit Kat Club, the band members performed wearing only
socks on their
penises, an idea formed by Kiedis. This gained the band notoriety, and club owners even began booking the group on the condition that they would perform in this manner. Irons and Slovak, however, decided to leave the Red Hot Chili Peppers in order to pursue a "more serious" future with their band Anthym, which by this time had been renamed
What Is This? Kiedis ultimately respected the decision, but felt the band would be lost without them. Kiedis and Flea hired drummer
Cliff Martinez from
The Weirdos and guitarist
Jack Sherman to fill Iron's and Slovak's places, respectively. Sherman was fired from the band following the tour and replaced by a returning Slovak.
1985–1988: Freaky Styley, The Uplift Mofo Party Plan, and death of Hillel Slovak Funk musician
George Clinton was hired to produce the band's second album,
Freaky Styley, as Slovak returned on guitar. The strong chemistry between Clinton and the Chili Peppers was felt instantly.
Freaky Styley was released in August 1985. It received only a bit more attention than
The Red Hot Chili Peppers with roughly 75,000 copies sold by year's end. What Is This? had finally disbanded, and Irons returned to the Chili Peppers in mid-1986 after Martinez was fired. Flea, Slovak and Kiedis especially were involved in heavy drug use and their relationships became strained. Flea recalled that "it began to seem ugly to me and not fun; our communication was not healthy". He was asked to leave the band in order to undergo
drug rehabilitation. During that time, the band won the
LA Weekly Band of the Year award, which prompted Kiedis to quit using heroin cold turkey. He visited his mother in
Michigan for guidance, who drove him to drug rehabilitation immediately after picking him up from the airport upon seeing his unhealthy appearance. Kiedis checked into a
Salvation Army rehabilitation clinic in
Grand Rapids, Michigan, an experience which he initially detested until he noted that the other people in the clinic were understanding of his struggles and were trying to help him. He moved in with his mother after twenty days at the clinic, a time which marked the first time he was completely abstinent from drugs since he was eleven years old. After Kiedis completed his stint in rehabilitation, he felt a "whole new wave of enthusiasm" due to his sobriety and wrote the lyrics to a new song titled "
Fight Like a Brave" on the flight home. He rejoined the Red Hot Chili Peppers in Los Angeles to record the album. Upon returning home, he began dating actress
Ione Skye, whom Flea met while appearing with her in the 1987 science fiction film
Stranded. Although Kiedis had recently become clean, his withdrawal symptoms increased and affected his musical contributions to the group. After fifty days of sobriety, Kiedis decided to take drugs again as a one-time attempt to celebrate his new music, which led to his resumed addiction. The recording process for the album became difficult, and Kiedis would often disappear to seek drugs. Producer Michael Beinhorn recalled that, "There were points in pre-production where I really thought the record wasn't gonna get made." Kiedis felt "excruciating pain and guilt and shame" when he would miss a recording session so he would try to write lyrics while searching for drugs; although the band members were upset by his drug use and frequent disappearances, they were impressed with his musical output at the time. After the international tour in support of
Uplift, Slovak died of a heroin overdose in 1988. Following Slovak's death, Kiedis fled to a small fishing village in Mexico and did not attend his funeral, considering the situation to be surreal and dreamlike. Although he found the death to be a shock, he initially was not "scared straight" and continued to use heroin. A few weeks later, his friend convinced him to check into rehab and visit Slovak's grave, which inspired him to get clean. Irons was unable to cope with Slovak's death and subsequently quit the band, saying that he did not want to be part of something that resulted in the death of his friend. Kiedis and Flea decided to continue making music, hoping to continue what Slovak "helped build". Following Slovak's death, Kiedis and Flea took some time to collect themselves, but decided to keep the band together. Guitarist
DeWayne McKnight and drummer
D. H. Peligro were added to replace Slovak and Irons. McKnight soon began to create tension within the group, as his style did not mesh with the rest of the band. Peligro, the former drummer of the punk rock band
Dead Kennedys, was a friend of
John Frusciante, an eighteen-year-old guitarist and avid Red Hot Chili Peppers fan. Peligro introduced Frusciante to Flea, and the three jammed together on several occasions. Kiedis was impressed with Frusciante's skill, and astonished by his knowledge of the Chili Peppers' repertoire. McKnight was fired, and Frusciante accepted an invitation to join the band.
1989–1993: ''Mother's Milk and Blood Sugar Sex Magik'' performing in
Amsterdam in August 1989 The Chili Peppers entered the studio, and completed recording of their fourth album, ''
Mother's Milk, in early 1989. Upon release, the album was met with mixed reactions from critics, but received far more commercial attention, peaking at number fifty-two on the Billboard'' 200. Although his band was experiencing greater success, Kiedis' withdrawal symptoms took a toll on his personal life. This led to the end of his two-year relationship with Ione Skye in December 1989: "I had managed to stay sober by not ingesting drugs, so my body had healed from all that torturous activity, but my mind still wasn't healthy enough to work out all the problems that come up in a relationship." In 1990, Kiedis was convicted for indecent exposure and sexual battery from an incident at
George Mason University in
Fairfax County, Virginia, in April 1989. He was ordered to pay a fine on both counts. Kiedis touched a woman's face with his penis after a concert at George Mason University in Fairfax County on April 21, 1989. The band sought to record their next album
Blood Sugar Sex Magik in an unconventional setting, believing it would enhance their creative output. The band's producer
Rick Rubin suggested
the mansion magician
Harry Houdini was rumored to have lived in, to which they agreed. A crew was hired to set up a recording studio and other equipment required for production in the house. The band decided that they would remain inside the mansion for the duration of recording, though Smith, convinced the location was haunted, refused to stay. During this stage, Kiedis began to write about anguish, and the self-mutilating thoughts he would experience as a result of his heroin and cocaine addiction. Rubin stumbled upon one of Kiedis's poems that would become the lyrics to "
Under the Bridge", and suggested Kiedis show it to the rest of the band. Kiedis was apprehensive because he believed the lyrics to be "too soft" and unlike the band's style. After singing the verse to Frusciante, they began structuring the song the next day. The two worked for several hours arranging chords and melodies until they both agreed it was complete. Up-and-coming bands
Nirvana,
Pearl Jam, and
Smashing Pumpkins also toured with them during their United States tour. The album was met with mixed reviews and was a major departure from the band's funk-punk sound. The tour to support the album was also met with mixed results. Chad Smith broke his arm prior to the launch of the U.S. tour in 1995 so it was delayed until early 1996. Near the tour's end, Kiedis was involved in a motorcycle accident, which left him with a broken arm. The tour ended with the band's final set being cut short due to a massive typhoon. The year 1997 was dubbed "The Year of Nothing" by the band's bassist Flea.
1998–2010: Californication, By the Way, and Stadium Arcadium The band regrouped in 1998 to begin writing for their seventh studio album; however, Navarro was now battling his own drug problems. This caused major tension between Kiedis and Navarro, who was fired from the band in early 1998. Flea informed Kiedis that he felt the only way the band could possibly continue is if Frusciante re-joined the band. In the years following Frusciante's departure from the Chili Peppers, he had developed a vicious addiction to both heroin and cocaine that left him in poverty and near death. He was talked into admitting himself to drug rehabilitation in January 1998. In April 1998, following Frusciante's three-month completion, Flea visited his former bandmate and openly invited him to re-join the band, an invitation Frusciante readily accepted. Within the week, and for the first time in six years, the foursome gathered to play and jump-started the newly reunited Red Hot Chili Peppers. The band released
Californication on June 8, 1999. Immediately following the release of
Californication, the band embarked on a
world tour to support the record, beginning in the United States. To culminate the US leg of their tour, the Chili Peppers were asked to close
Woodstock '99, which became infamous for the violence it resulted in. The band was informed minutes before arriving that the crowds and bonfires in the fields had gone out of control. Kiedis felt that "It was clear that this situation had nothing to do with Woodstock anymore. It wasn't symbolic of peace and love, but of greed and cashing in... We woke up to papers and radio stations vilifying us for playing 'Fire'." The writing and formation of
By the Way began immediately following the culmination of ''Californication's
world tour, in the Spring of 2001. As with Californication'', much of the creation took place in the band members' homes, and other locations of practice, such as a recording studio stage. Kiedis recalled of the situation: "We started finding some magic and some music and some riffs and some rhythms and some jams and some grooves, and we added to it and subtracted from it and pushed it around and put melodies to it." For Kiedis, "writing
By the Way...was a whole different experience from
Californication. John was back to himself and brimming with confidence." Kiedis noted that during the recording process of the album "everybody was in a good mood. There was very little tension, very little anxiety, very little weirdness going on and every day we showed up to this funky room in the Valley, and everyone felt more comfortable than ever bringing in their ideas." The album was released on May 9, 2006. Following a hugely successful world tour to support
Stadium Arcadium, the band decided to take an extended year long break from music in 2008. According to Kiedis, there was a collective decision "not [to] do anything Red Hot Chili Peppers-related for a minimum of one year. [...] We started in 1999, with the writing and the recording of
Californication, and we didn't really stop until the tour ended last year. We were all emotionally and mentally zapped at the end of that run." During the break, Frusciante departed amicably with the band in July 2009 (although it wasn't publicly announced until December 2009).
Josh Klinghoffer, a touring guitarist for the Chili Peppers and often collaborator with Frusciante was hired as his replacement.
2011–2015: ''I'm with You'' and Rock and Roll Hall of Fame induction On August 26, 2011, the Red Hot Chili Peppers released their tenth album, ''
I'm with You. On December 7, 2011, the Red Hot Chili Peppers were named 2012 inductees into the Rock and Roll Hall of Fame. Kiedis said it was very emotional and the first person he told was his father, who cried when hearing the news. On January 11, 2012, the Chili Peppers announced that they were forced to postpone the U.S. leg of their I'm with You tour'' due to multiple foot injuries suffered by Kiedis. Kiedis has been battling through foot injuries since 2006 when he injured his foot onstage and finally was able to have surgery during a break in the band's tour in January 2012. During the surgery, Kiedis had a crushed
sesamoid bone removed and a detached flexor tendon repaired. The band was able to resume their tour and kicked off the U.S. leg on March 29, 2012. The tour in support of ''I'm with You'' ended in April 2013 and the band continued touring into mid-2014 which included a halftime performance with
Bruno Mars at the
Super Bowl in February 2014. In November 2014, Kiedis set out on a mini-book tour to promote the Chili Peppers book,
Fandemonium. This included book signings, a Q&A and an appearance on
The Tonight Show with Jimmy Fallon where Kiedis sat in the entire show with
The Roots performing Chili Peppers songs. Kiedis received the
George and
Ira Gershwin Award for Lifetime Musical Achievement, presented at the
UCLA Spring Sing on May 16, 2015. Kiedis' mother, Peggy Noble Idema, commented on her son receiving the award by saying "This really makes me proud. Both my parents and Grandpa Idema were huge Gershwin fans. I grew up with their music." Following his acceptance speech, Kiedis was joined on stage by his Chili Peppers bandmate Josh Klinghoffer for an acoustic performance of "
Otherside", a cover of
Sly and the Family Stone's "
If You Want Me to Stay" and "By the Way".
2016–present: Health scare, The Getaway, Unlimited Love, and Return Of the Dream Canteen star for the
Red Hot Chili Peppers on
Hollywood Boulevard near
Amoeba Music On May 14, 2016, the band were forced to cancel their headlining slot at the annual
KROQ Weenie Roast, as Kiedis was rushed to the hospital prior to the band appearing on stage. It was confirmed that Kiedis was suffering from
intestinal flu and was expected to make a full recovery; however, the band was forced to postpone their
iHeartRadio album preview show on May 17, 2016, which was rescheduled for May 26. Kiedis and the Chili Peppers returned to the stage on May 22, 2016, in
Columbus, Ohio. In a May 20, 2016 interview with
Entertainment Tonight Canada, his first since being released from the hospital, Kiedis said that his illness was brought on by an "inflammation in my guts" which he said was complicated by a recent stomach virus and existing scar tissue from previous hernia operations which required his stomach being pumped at the hospital. During a break in filming of
The Late Late Show with James Corden carpool karaoke segment which aired on June 14, 2016, and featured the band singing karaoke to their music with the host while driving through Los Angeles, Kiedis performed emergency
CPR on a baby. "A woman came out of her house, holding a child saying, 'My baby, my baby, my baby can't breathe!'" Kiedis said. "The woman thrust the baby into my arms, the baby was not breathing and I thought, 'I'm gonna try and do a little baby CPR real quick, see if I can get some air in this kid. So I started rubbing the belly, bubbles came out of the mouth, the eyes rolled back into place, the ambulance showed up and I handed the baby over, who was now breathing and fine, and we went back to Carpool Karaoke." The Red Hot Chili Peppers released their eleventh studio album,
The Getaway, on June 17, 2016. On October 20, 2018, Kiedis, who was attending the
Los Angeles Lakers game with Flea, was ejected from the game for swearing and giving the middle finger to
Chris Paul of the
Houston Rockets. In December 2019, the Red Hot Chili Peppers announced that guitarist John Frusciante would be returning to replace Josh Klinghoffer. As of May 2021, the band had nearly completed their twelfth studio album
Unlimited Love and on October 7, 2021, the band announced dates for the
Global Stadium Tour beginning in June and concluding in September, later extending the tour to the following February. The tour, in support of the album, featured the band's first ever headlining stadium shows in the U.S. Unlimited Love was released on April 1, 2022. On December 20, 2021, Kiedis appeared at
Dave Navarro and
Billy Morrison's third annual Above Ground benefit concert in Los Angeles, where they performed a cover of
Lou Reed's "
Walk on the Wild Side". This marked the first time Kiedis and Navarro performed together in 24 years since Navarro was fired from the Red Hot Chili Peppers. On October 14, 2022, The Red Hot Chili Peppers released their thirteenth studio album,
Return of the Dream Canteen. On May 16, 2025, it was reported by
Deadline that a documentary on the band's formative years was being secretly screened at the
Cannes Film Festival and was looking for select buyers in both New York and Los Angeles. A festival premiere for the film will be planned for either fall 2025 or early 2026. The documentary, which is being co-produced by Hillel Slovak's brother James, will center on the deep childhood bond between Anthony Kiedis, Flea and Hillel Slovak and features various interviews from current and past band members. As of February 2026, the Chili Peppers are currently in the writing process for their fourteenth studio album. “We’ve been writing music together, recording at John Frusciante’s house, and the music feels great. Ultimately, once we start playing, it’s about… just catching a magic groove and doing it good" Flea said. ==Other projects==
