theme, 2006). Today, Chaka performs live jazz gigs in her native Japan and lend her voice to many famous Japanese artists. Among them, she recently participate in chorus for the Tsuyoshi Doumoto' solo unit "Endlicheri Endlicheri" (album "Coward", single "The Rainbow Star", all along "The Rainbow Star" Tour) and in the single "Man & Woman" from Chage & Aska. History Chaka (Mami Yasunori) met Masaya Matsuura in 1983, and two years later they released an independent album under the band name Playtechs. At this point they were merely an indies unit, and performed no live shows for the album. However, this became the basis of what would become Psy・S. Psy・S debuted in 1985 by releasing their first Psy・S album, Different View, with Sony Music. Their first single from the album, Teenage, went on simultaneous sale. This was their major debut, and a music video was created for Teenage. Psy・S' activity and popularity continued through the late 80s to mid 90s, where their music was used on TV shows ("Mamatte kirei!?" – 1991), anime (To-y – 1987, and City Hunter – 1988), and movies (Sweet Home – 1989). In particular, Masaya Matsuura was given full musical supervision over the sound of the acclaimed anime adaptation of Atsushi Kamijo's manga To-y (an anime set-piece developed by a "dream team" of famous Japanese names in terms of directing, character design and art direction), creating a soundtrack which has garnered much praise in anime journalism. As the Anime News Network notes, "No mention of TO-Y is complete without speaking of the music, which plays like a best-of album of Japan's progressive pop scene… For TO-Y, Psy・S' amazing opening and ending themes, Lemon no Yuuki and Cubic Lovers, are as essential to the show as the characters themselves." During their 1985–1996 history, Psy・S released eleven original albums, one live album, three "best of" collections, seven videos and a DVD. Finally, in the June 1996 issue of Japan's PC Music magazine, Masaya Matsuura officially announced the breakup (later referred to as the "demise") of Psy・S. In 2002, a CD collection of their best singles, Golden Best (Singles+), was released, and a live DVD (the band's first) was released in 2005 containing footage from their 1988–1989 Non-Fiction Tour, when the band were at the height of their popularity.
