Sound Horizon (サウンドホライズン), abbreviated by fans as Sanhora (サンホラ), is a Japanese band formed in 2001 by composer and multi-instrumentalist Revo, who serves as the group's only consistent member. Their debut album, Chronicle, was released on 30 December and distributed at Comiket 61. The band refers to itself as ''幻想楽団' (or the 'fantasy band'). The collective fan base is known as the 'Sound Horizon Kingdom'. The music of Sound Horizon is generally presented in omnibus style; all of their releases have been in the form of concept albums. For tie-up material and releases without an overarching original story, the group performs under the name Linked Horizon. Both male and female vocals are utilized within Sound Horizon, with some singers being frequent collaborators. Usage of spoken word sections in the form of narration is common in their songs and can be heard in a variety of different languages. This narration is often reminiscent of anime due to the involvement of prominent voice actors/actresses in the group. A number of stylistic influences are also apparent in their music; these include progressive/symphonic rock, jazz, pop, opera, and metal. The group's lyrics are often mysterious and metaphorical and contain a variety of fantastical themes. Members: Other than Revo, the lineup of the group may consist of dozens of singers, musicians, and/or voice actors at any given time.
