Previous members of Sleep Chamber have included Thomas Thorn, Michael Moynihan, Jonathan Briley and Elaine Walker.
[2] After an extended absence, Sleep Chamber returned in 2008 with a new lineup, a slew of new releases, and a revised name, SLEEPCHAMBER.
Walker's band DDT had frequently played with Sleep Chamber at local venues around the Boston area.
[7] A successful tour of California resulted, featuring Zewizz, Walker, Swanson and longtime friend and collaborator Difrancisco.
Although pleased with the lineup, Zewizz was aware that Walker's commitment was to her other projects and that she did not plan to stay with Sleep Chamber.
[8] Zewizz then introduced another Sleep Chamber lineup, including new drummer Jay Keegan and songwriting duo Andrew Woolf and Craig Wien, as well as help from previous guitar sideman Swanson.
This lineup was the last recording version of Sleep Chamber, performing on several releases, including Some Godz Die Young and Sonorous Invokations ov Brian Jones – the latter being solely Zewizz and Woolf.
However, drug addiction, personal problems, and constant touring had ceased Zewizz's steady flow of new music by the end of 1995.
[9] Real problems began earlier in 1995, when Zewizz was questioned regarding the murder of Karina Holmer, a Swedish au pair living in Boston.
The accusation, coupled with a growing heroin addiction, quickly began to destroy the band and drove Zewizz away from bandmates and friends.
Unable to get commitments from the current lineup of Sleep Chamber, Zewizz took on two new members (Scott Walker and Tyler Newman) for the German tour, as well as Barbitchuette dancer "Lulu".
Seeing his life beginning to spiral out of control, friends of Zewizz tried to help him when he returned from the German tour, putting on a benefit concert.
[13] Since 2009, SLEEPCHAMBER has released over five CDs (on Klanggalerie, Old Europa Cafe, and Zewizz's own label Inner-X-Musick), a four-LP box set with a 7-inch single and booklet titled SixSixSix (on Vinyl on Demand), and participated in several compilations.
This first live performance featured Zewizz, Avakian, and Sparks, along with percussionist Tick and backing vocalist Zora.
[14] In 2009 Sleep Chamber released "Soundtrax" a collection of Soundtrack pieces, also from Austria Label Klang Galleries "Sorcery Spells and Serpant Charms".
