I've been searching and asking around, but there really isn't much info about Cosmos on the net. Can anybody help at least name the other members? I've found some Keiko Matsui solo albums, but they're really a let-down after hearing this material. Anyway, here are three more albums from Cosmos:
Can Can Can! (1982 I think, but this site says '85)
Bourbon Suite (1982)
夢想都市/ "Urban Fantasy" (1985)
A bit confused about this one's english title and year.
