The Killers (2002–present) While performing with the Negative Ponies, Stoermer met
Brandon Flowers and
Dave Keuning, who were performing as an early incarnation of the Killers. He was a fan of the band's unique sound and was often present at the band's gigs." They even asked me to join the band as a guitar player, because originally – at least according to Dave – they wanted to build a five-piece, possibly more like the Strokes with a keyboard," said Stoermer in 2016. "I was first asked to be a second guitar player and I casually mentioned I also play bass. And then one day I got the call from Dave." In September 2002, he was offered the opportunity to become the band's permanent
bass player, which he accepted and completed the band's lineup along with
Ronnie Vannucci Jr. The band's seven studio albums each reached No. 1 on the
United Kingdom Albums Chart and garnered the band seven
GRAMMY Award nominations and seven
BRIT Award nominations.
Production work and collaborations (2010–present) In 2010, Stoermer produced rock band
Howling Bells' third studio album,
The Loudest Engine. The album was recorded at
Battle Born Studios in Las Vegas, Nevada, and was released in September 2011. On September 24, 2014, Stoermer performed "
Let It Down" and "
Ballad of Sir Frankie Crisp (Let It Roll)" with
Dhani Harrison on
Conan during George Harrison week. In late 2014 and early 2015, Stoermer played bass guitar on tour with
the Smashing Pumpkins along with
Billy Corgan,
Jeff Schroeder and
Brad Wilk. A Smashing Pumpkins fan since his teen years, Stoermer received a call from Corgan – who had become a casual acquaintance after their respective bands played a few shows together in recent years – to join the touring line-up in support of the Smashing Pumpkins' then-new album
Monuments to an Elegy. The strength of the new material convinced Stoermer to accept the offer. "In addition to the nostalgia aspect, I also had to hear the new music, which I think is great. If the new music wasn't up to par, I wouldn't be doing it. I felt like, yeah, it was one of those things I had to do", he said. On December 1, 2014, Stoermer performed "
Maida Vale" with Smashing Pumpkins on BBC Radio 6. On December 11, 2014, he performed "
Being Beige" with Smashing Pumpkins on
Jimmy Kimmel Live. On April 3, 2015, he performed "Drum + Fife" with the Smashing Pumpkins on
The Tonight Show Starring Jimmy Fallon.
Hiatus with the Killers (2016–present) On May 24, 2016, the Killers announced that Stoermer was taking a break from touring "to pursue other educational goals and releasing a solo album." The statement emphasized that Stoermer was still involved in working on the band's fifth album,
Wonderful Wonderful, and that he may still occasionally perform live with them in the future. Stoermer elaborated further in an interview: "I'm taking a class online right now. The reason why I'm doing that is to take a break, but not exclusively. It's a combination of a lot of things. I've been doing the Killers since 2003 and I think about a thousand shows. I just needed to step away a while from that." However, he did contribute to the song selection of their 2023 compilation album,
Rebel Diamonds, and performed with the band during their
20 Years of Hot Fuss residency in 2024 and 2025. Stoermer also performed with the band on the single "
Bright Lights," released prior to the residency in August 2024. Stoermer was present with The Killers,
Waddy Watchel and
David Letterman for
The Rock and Roll Hall of Fame 2025 induction ceremony on behalf of
Warren Zevon. Stoermer performed with the Killers Live at Freely Fest at Bridgestone Arena in Nashville, 8th April 2026.
Solo career Another Life (2011) Stoermer's debut studio album
Another Life was released on November 1, 2011, as a self-release on St. August Records. It was available for free download via markstoermer.com, and sold on CD and vinyl on January 24, 2012. It was also released on iTunes the same day along with two bonus tracks. Stoermer recorded the album in early 2011 with the help of Glenn Moule and Joel Stein, from Howling Bells, and Jason Hill from
Louis XIV. The album was mixed by Robert Root and mastered by
Bob Ludwig.
Dark Arts (2016) Dark Arts was released on August 5, 2016, as a self-release on St. August Records. The album was written and produced by Stoermer.
David Hopkins was also involved in writing and production. The album was mixed and engineered by Robert Root. The first single "Spare the Ones that Weep" was released on July 22, 2016. Soon after the second single "Are Your Stars Out?" was released on July 29, 2016, and was featured on
Billboard along with an interview in which Stoermer talked about his inspiration for the song's lyrics. The album is noticeably different from the work he is known for with the Killers, consisting mainly of sixties psychedelic foundations.
Blood and Guts / Beautiful Deformities 7-inch (2016) The
Blood and Guts / Beautiful Deformities 7-inch was a limited edition vinyl released for Halloween 2016 with only 100 copies made that were decorated with one of ten unique designs and only ten of each design was produced. The release featured the single
Blood and Guts (The Anatomy Lesson) on one side, and
Beautiful Deformities (The Monastic Controversy) on the other. 100 additional copies were manufactured and given away to fans through the Secret Door, a hidden page on Mark's website, initiated as a "thank you" note. These copies didn't have the same picture disc artwork as the other 100 copies.
Shows In support of
Dark Arts, Stoermer invited several musicians to form the Hownds, a five-person band including
David Hopkins (keyboards), Nigel Ledgerwood (rhythm guitar), Ben Lecourt (drums) and Erik Paparozzi (bass). They performed five shows in Las Vegas and Los Angeles.
Filthy Apes and Lions (2017) Filthy Apes and Lions was released on vinyl on October 13, and digitally and on CD on November 17, 2017 through Stoermer's label St. August Records. The title track "Filthy Apes and Lions" was the first single released on October 13, 2017. "Beautiful Deformities" was the second single, released on November 11, 2017.
Filthy Apes and Lions was written and produced by Mark Stoermer and David Hopkins with Robert Root. The album was mixed and engineered by Robert Root. Sprinkled with sixties psychedelic foundations, jazz fusion, and progressive rock, the album is very different from the work he is known for in
the Killers. Stoermer talked about the songwriting process behind the single "Filthy Apes and Lions": I was doing a stream-of-consciousness, surrealistic exercise where you just write out whatever's on the top of your head, and then I started creating rhymes, not really knowing where I was going, and then that's where I got the lyrics for the song [...] "Filthy Apes and Lions." ==Artistry==
