Sleep Chamber Biography (Wikipedia)
Sleep Chamber is an American industrial band fronted by John Zewizz. The band is known for using S&M, bondage and magic imagery on their artwork, during their performances, and within their lyrics. Formed in 1981 by high school friends Zewizz, Eugene Difrancisco, and Phil Brosseau, over the years the Sleep Chamber lineup has changed many times with Zewizz being the sole permanent member. Previous members of Sleep Chamber have included Thomas Thorn, Michael Moynihan, Jonathan Briley and Elaine Walker. Since the beginning, Zewizz has stated that the constant lineup changes are because Sleep Chamber is not a "band", but rather a "concept".
From 1982 to 1999, Sleep Chamber put out a considerable volume of music (releasing over 70 recordings, and participating in over 35 various artists releases). After an extended absence, Sleep Chamber returned in 2008 with a new lineup, a slew of new releases, and a revised name, SLEEPCHAMBER.
