Slipstream was one of the many projects to emerge from the Spacemen 3 drone-rock camp -- singer/guitarist Mark Refoy first appeared on the Spacemen's 1991 finale Recurring, and later co-founded Spirtualized with Jason Pierce. After the completion of the 1992 Spiritualized masterpiece Lazer Guided Melodies, Refoy exited the group to form Slipstream, a more pop-oriented concern also comprising fellow Spiritualized alum Jon Mattock on percussion as well as guitarist Ian Anderson, bassist Steve New and drummer Steve Bes; the group debuted in the summer of 1994 with the single "Sundown," following with a series of seven-inch releases before recording their 1995 self-titled debut. A singles collection, Side Effects, appeared later that same year, and in 1997 Slipstream released their second proper LP, Be Groovy or Leave. ~ Jason Ankeny, All Music Guide
