Aldious (Japanese: アルディアス?, Hepburn: Arudiasu) is a Japanese all-female power metal band from Osaka, formed in 2008 by guitarist Yoshi and vocalist Rami. After a few member changes, they released their debut EP Dear Slave the following year and soon after formed their own record label, Bright Star Records. Their first album Deep Exceed (2010) reached the top 15 on the Oricon chart, as did their second Determination (2011). However, founding member Rami announced she was leaving the group in June 2012 for health reasons and new vocalist Re:NO joined Aldious just one month later. They produced their third album District Zero in 2013 and it became their highest-charting release to date, reaching number 7. Their fourth album Dazed and Delight (2014) peaked at number 20, and their fifth Radiant A was released in Japan in December 2015 and later became their first album released in Europe in 2017. Aldious have been labelled pioneers of the "Girls Metal Band Boom" that began in Japan in the 2010s.[1][2]


Guitarist Yoshi and vocalist Rami formed Aldious in Osaka in June 2008.[3] The name Aldious was created by Rami shortening the phrase "Ultimate Melodious."[4] In November they took part in the compilation album Red Hot Burning Hell Vol.16,[5] soon after which guitarist Ruki and bassist Sawa left. In January 2009, Toki and Kaze joined as guitarist and bassist respectively, later the band released their debut four-track EP Dear Slave on November 7.[5] Kaze left in December, and drummer Aruto joined in January 2010. March saw the return of Sawa on bass and around this time Aldious formed their own record label, Bright Star Records.[5] Their first single "Defended Desire", released July 7, reached the number 4 position on Oricon's Indies chart and number 49 on its regular chart.[5][6] In April, Bright Star became a sublabel of Spinning and the band released their debut album Deep Exceed on October 13, 2010.[3] It reached number 15 on the charts.[7]

Determination, the band's second album, was released on October 12, 2011 and reached number 13.[7][8] The song "Spirit Black" was used as the ending theme song of the Fuji TV show Shimura Ken (志村軒). The album's single, "Mermaid", was previously released on April 6 and earned the number 20 position.[6] On June 29, 2012, it was announced that vocalist and co-founder Rami would withdraw from the group due to health concerns.[9] Only a month later, on August 3, Re:NO was announced as Aldious' new singer.[10] This line-up's first release was the single "White Crow" on November 14, which reached number 19 and was co-produced by Akihito Kinoshita, guitarist and leader of the veteran heavy metal band Saber Tiger.[6][11][12] On May 15, 2013, Aldious released their third album District Zero, which became their first release to break the top-ten.[7][13] Its song "Scrash" became the ending theme song for the TBS TV show Ranking Kingdom (ランク王国) from June to July. It was reported that for the album the band intentionally toned down their appearance and aimed for a "pure metal sound", so as to be recognized for their musicianship rather than being an all-female band.[14]

Their fourth single and first double A-side, "Dominator / I Don't Like Me", was released on October 9 and is the group's highest charting, having reached number 12. Their next single, "Other World", peaked at number 22 and their fourth album, Dazed and Delight released on June 18, 2014, has been their lowest charting, only reaching the 20 position.[6][7] In September 2014, Aruto announced she was leaving Aldious and music entirely due to her upcoming marriage, which would see her moving far from Tokyo, where the band is based. She stayed with the group until the end of November 2014.[15] Aldious announced their new drummer Marina, step-daughter of American drummer Terry Bozzio,[16] on April 19, 2015. They also left their parent record label Spinning at their own request.[17]

Aldious released the triple A-side single "Die for You / Dearly / Believe Myself" on July 8, 2015. The band released their fifth album Radiant A on December 2. It is their first on the VAA (Village Again Association) label, under their own sublabel that shares the Radiant A name, and their first featuring new drummer Marina, with a limited "Marina Edition" of the album available exclusively through HMV Group and Loppi.[18] A second triple single, "Female Warrior / Nostalgic / Fragile", was released on October 26, 2016. Throughout the year the band played at several major festivals and concerts such as Summer Sonic,[19] Loud Park,[19] Visual Japan Summit,[20] and hide Birthday Party.[21] Radiant A became Aldious' first album released overseas when it was published in Europe by JPU Records on March 17, 2017 with two additional live tracks.[22]

The group released their sixth album, Unlimited Diffusion, on May 10, 2017.[23]
