Sound Horizon

Sound Horizon is a Japanese symphonic rock musical group with composer Revo (musician) as the leader and only permanent member. They describe themselves as a "fantasy band" and have released works that closely resemble classical suites. Their songs often revolve around historical events and classic fairytales. When creating music based on other people's stories, the band uses the name Linked Horizon.

History
Sound Horizon began with Revo releasing his music creations on the internet on his website in the late 1990s. In 2001, Sound Horizon participated in Comic Market as part of a dōjin music circle and released their first story CD, Chronicle, an all-instrumental track CD, with occasional narration, background chorus and sound effects. The inclusion of actual singing began from their second release (Thanatos) onwards. Their subsequent works were released at Comic Market and M3.

Sound Horizon's first major release was in 2004, with the album Elysion ~Rakuen e no Zensōkyoku~ (lit. Elysion ~Prelude to Paradise~). Their first maxi-single, "Shōnen wa Tsurugi o...", which was released in 2006, includes "Shūtan no Ou to Isekai no Kishi ~The Endia & The Knights~", the theme for the PlayStation 2 simulation RPG Chaos Wars, and "Kamigami ga Aishita Rakuen ~Belle Isle~", the opening theme for the MMORPG Belle Isle.

Although Aramary was their main female singer through the Elysion album, her departure afterward led Sound Horizon's style to shift quite a bit, to having many vocalists, rather than just one main female one (previously Aramary) and one main male vocalist (Jimang). Revo himself also tended to sing more often in the later albums, beginning with Roman.

On September 3, 2008, Sound Horizon released the album Moira. The album featured Takashi Utsunomiya of TM Network as one of the vocalists. Moira debuted at No. 3 on the Oricon weekly album charts, selling over 45,000 copies in its initial week.

Sound Horizon released the single "Ido e Itaru Mori e Itaru Ido" on June 16, 2010. The single featured guitarist Marty Friedman and Vocaloid Hatsune Miku, along with a beta voicebank for Vocaloid known as "Junger März PROTOTYPE β".

In 2012, Revo began a new project called Linked Horizon, beginning with his work on the score for the Nintendo 3DS game Bravely Default: Flying Fairy, a series of EPs and album. In 2013 and subsequent years, Linked Horizon performed the first, second, third, fifth and eighth opening themes, as well as the fourth and series finale ending themes, for the anime adaptation of Attack on Titan along with a series of EPs and albums.

In June 2014, Revo also composed the first opening theme of Sailor Moon Crystal, "Moon Pride".
