Zilch (stylized as zilch or 零) was a rock supergroup that was formed in 1996 by Hideto "hide" Matsumoto (X Japan), Ray McVeigh (formerly of The Professionals), Paul Raven (Killing Joke), Joey Castillo (Danzig and Queens of the Stone Age) and Kazuhiko "I.N.A." Inada (hide with Spread Beaver).
Before the release of their first album, 3.2.1., the group had already faced a major setback, as frontman hide died in May 1998. The band continued to perform live with the help of several guest musicians and released a remix album, Bastard Eyes, based on their debut. They went on to release another studio album, SkyJin, and two singles, "Mimizuzero" and "Charlie's Children."
Zilch disbanded in 2002, and Raven died in 2007.
