What is "psy-s"

Psy・S [sáiz] (often written as "Psy-S" or "Psy S" in English due to the lack of the Japanese dot "・" on most western keyboards) was a popular Japanese progressive pop/ rock band, formed in 1983 by Masaya Matsuura alongside female vocal powerhouse Chaka (a pseudonym used by Mami Yasunori). After Japanese hits and successes throughout the late 1980s and early 1990s, they disbanded in 1996.

The musical style of Psy・S was an experimental mixture of electronic synthesizers, highly accomplished electric guitar riffs, and haunting, piercing vocals. Psy・S is perhaps best known in the West for their significant role in the soundtrack of the cult anime title To-Y (adapted from Atsushi Kamijo's popular 1980s manga). The anime's opening theme, Lemon no Yuuki, and ending song Cubic Lovers are seen amongst Western anime fans and Jpop enthusiasts as two of Psy・S' all-time greatest songs. Frontman Masaya Matsuura went on to create several famous video games for the Sony PlayStation.
