Coaltar of the Deepers

In early 1991, the band was formed in Tokyo by frontman Narasaki. During that time, they recorded demo tapes including most of the songs eventually incorporated into their first release "White EP," on Strange Records. The EP had former member Watanabe on vocals while Narasaki played guitar. The band's activity was silent until the end of 1992, when they released their second EP, "Queen's Park all you change" on Stomly Records. The band gained some recognition which showed the release of their third EP, "Sinking Slowly" a month later.

The band had little activity until the release of their first album, The Visitors From Deepspace in 1994 on Victor Records. In 1997 the band released new material; another EP, "Cat EP" was released on ZK Records. In 1998, the band released "Submerge", an album full of remixes, rare and new songs and a best-of album, Breastroke. A new EP Dog EP preceded their next full-length album in 2000, Come Over to the Deepend (a play on the band's abbreviation COTD).

In the style of Come Over to the Deepend, the band released Robot EP in 2001, which was followed by the album No Thank You. The album marked a new era for the band as they experimented even more heavily with electronic beats and noises. A new album was released in 2002, newave. With their small U.S. tour in 2003, Narasaki showed interest in an even heavier sound and released the Mouse and Penguin EPs.

After the release of the 2004 EPs, Narasaki composed the musical score for the anime Paradise Kiss and worked on his side project Sadesper Record, which released a full-length album earlier that year. In 2006, the band continued working on a new EP and album, both of which were released in mid-2007.[2]

Narasaki, while being the leader of the band, has been an active musician in Japan. In 1998, he created the side project Sadesper Record which is more electronic based than Coaltar of the Deepers. In 2004, the second Sadesper Record album was released. He has also contributed to the band Tokusatsu in which the group created the soundtrack for the movie Stacy: Attack of the Schoolgirl Zombies.

Narasaki has also contributed to the shoegaze band Astrobrite. He contributed a remix of the track 'Snowflakes' to the spin-off of the video game Persona 4, Persona 4: Dancing All Night for the PlayStation Vita.[3] Narasaki also takes credit for producing all the background music for the anime adaptation of Deadman Wonderland
