Summary

The Disappearance of Hatsune Miku is the first major commercial album by VOCALOID producer CosMo@BousouP (CosMo@BousouP), released by Exit Tunes in 2010. The album compiles fourteen tracks featuring Hatsune Miku, including many of the producer’s best-known works alongside newly arranged material.

The album is named after “The Disappearance of Hatsune Miku” (初音ミクの消失), a song that became one of the most recognisable pieces in the VOCALOID community. Famous for its exceptionally fast lyrics and demanding vocal programming, it remains one of Hatsune Miku’s signature songs and has appeared in numerous rhythm games, concerts and official compilations.

Musically, the album showcases CosMo@BousouP’s distinctive style, combining extremely fast tempos, complex arrangements and technically challenging vocal sequences with narrative-driven compositions. It represents a defining period in early VOCALOID music, when independent internet producers were beginning to receive commercial CD releases through labels such as Exit Tunes.
