Formed in 1994 in Hamilton, Ontario, their first album, 1995's Somnium, was critically successful but commercially was a non-factor. Three more albums were released before the band broke up in 2001: There's Always Someplace You'd Rather Be (1998), Else (1999), and The Sound of The Colour of The Sun (2001). Sianspheric reformed in 2005 and released RGB, a live concert DVD, and a new single, the 7-inch I Wouldn't Expect You To Understand.

Formerly known as SIANspheric4.
