2001–2002: Formation and indie days Galneryus was formed in 2001 by guitarist and
bandleader Syu (Valkyr,
Animetal, Aushvitz) and vocalist Masahiro "Yama-B" Yamaguchi (AxBites, Rekion, River End and Gunbridge). While at a live house in Kujō,
Osaka, Syu heard fellow
Kansai-native Yama-B on the radio and knew he wanted to work with him. Both veterans of the metal scene, Syu and Yama-B formed the band with the intention to "express both of their musical tastes/ideas" and so they started looking for additional members to complete the lineup. They recruited A on keyboards (who had previously played with Syu in Valkyr), Shōgo Himuro on bass, and Toshihiro "Tossan" Yui (formerly of Cemetery, Honey Quest) on drums. In October 2001, the band released a two-track
demo titled "United Flag". It was self-produced and released independently, but started gaining the attention of both fans and independent record labels as well. After playing with other metal bands like Fairy Mirror, Mephistopheles, Galactica Phantom, Mastermind, and
Concerto Moon, Galneryus went back to the studio to record an
EP.
Rebel Flag was released through the independent label Iron Shock in August 2002. The EP again used support musicians to fill the band slots, with Shōgo Himuro again on bass, Toshihiro Yui again on drums, and Yoshinori Kataoka on keyboards. After this EP, the band started receiving several record deals and started touring more. In 2003, they were invited to play the Melodic Metal Festival in Japan which featured
Swedish power metal band
Dragonland, as well as Australia's
Dungeon. As a result, Dragonland invited Galneryus to play with them the next time they toured Japan. Galneryus was also invited to perform on two metal compilation cover albums with other bands such as Masaki Project,
Saber Tiger, and Mephistopheles. Galneryus performed the song "Black Diamond" (originally from
Finnish power metal band
Stratovarius) on the compilation album
Stand Proud! III and performed the song "Soldier of Fortune" (from Japanese heavy metal band
Loudness) on the compilation album
Japanese Heavy Metal Tribute Tamashii II. For these songs, the band used supporting musicians Toshihiro Yui on drums, Yusuke on bass, and Yuhki on keyboards. Both compilation albums were released simultaneously in December 2002 on the same day through Iron Shock and distributed through the record label
VAP.
2003–2007: Gone major and formal members VAP itself signed Galneryus and the band set to work on writing and recording their full-length debut album
The Flag of Punishment which featured all 5 EP songs re-written and re-recorded and also cover art by famed
Final Fantasy artist
Yoshitaka Amano. was recruited to fill in for bass. The band shortly after released their fourth album
One for All - All for One on August 22, 2007. On October 27, they released their first cover album
Voices from the Past. Galneryus then debuted on
iTunes Store, making their material available worldwide.
2008–2011: Yama-B's departure and Resurrection In February 2008, both sides of their double A-side single "Alsatia/Cause Disarray" were used as the opening and ending themes for the six-episode
anime series
Rin ~Daughters of Mnemosyne~. On October 10, 2008, it was announced that vocalist Yama-B was leaving the band at the end of the Back to the Flag tour. The decision was made during the recording/releasing of their fifth full album,
Reincarnation. According to Yama-B's note left to the fans on Galneryus' official site, he left due to the band's growth and change. While Yama-B "likes to stick to a certain set of rules, concepts", particularly Syu would spontaneously abandon a style in order to incorporate new inspirations. In September 2009, bassist Yu-To left the group, and Sho and Taka officially joined. This line-up had their first performance at
Loud Park Festival 2009. On April 21, they released the
digital EP Beginning of the Resurrection, which contains a cover of Sho's 1992 hit single "You're the Only...". They released their sixth full-length album,
Resurrection, and its cover features the series' main character. Galneryus' next single, "Hunting for Your Dream", was used as the second closing theme of the new
Hunter × Hunter anime adaptation. Both
Kizuna and the Type A edition of "Hunting for Your Dream" include a cover of Ono's solo song "
Departure!"; the former features an English version, and the latter a Japanese one. Their eighth studio album
Angel of Salvation was released on October 10, 2012, and reached number 17 on the
Oricon chart. The title track, which interpolates "
Violin Concerto in D major, Op. 35" by
Pyotr Ilyich Tchaikovsky, is 14:42 minutes long, twice as long as the version featured in its music video, and features Akane Liv (of Liv Moon) performing backing vocals. Yuhki, alongside the band, collaborated with acclaimed video game composer
Daisuke Ishiwatari to create the soundtrack for the Japanese
fighting game BlazBlue: Chrono Phantasma, which released in arcades in November 2012, performing arrangements for most of the series' original themes. On May 22, 2013, Galneryus released their first self-cover album,
The Ironhearted Flag Vol. 1: Regeneration Side. It became their highest-charting release to date, reaching number 15, and is part of their 10th anniversary celebration, which also included a tour from June 7 to 30. Galneryus embarked on their first European tour in July 2014. Beginning in
Germany, the four date tour also took them to
France before finishing in
Spain. They released the album
Vetelgyus in September 2014. Galneryus' song "Attitude to Life" was used as the ending theme for the anime television series
Laughing Under the Clouds. Galneryus released
Under the Force of Courage, their tenth studio album and first
concept album in December 2015. It became their highest-charting studio album, reaching number 13. In June 2016, it was announced that drummer Jun-ichi had amicably left Galneryus after 13 years. Syu later said that since Jun-ichi lived in Osaka, taught at a music school and had other musical projects, it had become difficult for him to balance them all as Galneryus' activities grew. It continues the concept of their previous album, On June 2, 2020, Galneryus announced that Fumiya had left the band. They also revealed his replacement, Lea of the band , who claimed to be influenced by both Jun-ichi and Fumiya. The band released the albums
Union Gives Strength on June 16, 2021, and
Between Dread and Valor on March 1, 2023. Both are referred to as "special albums" due to the number of songs they include, but Syu said there is no particularly big meaning behind it and they are essentially regular studio albums. ==Musical style and lyrical themes==
