Tapeworm
History
After The Downward Spiral tours in 1996, Danny Lohner and Charlie Clouser approached Trent with music ideas that Trent felt did not fit in with his vision of the band, but instead agreed to collaborate and work on the material as a side project, with each member having equal say in decisions. The band eventually became a supergroup of sorts including, among others, Maynard James Keenan (Tool, A Perfect Circle), Page Hamilton (Helmet), and Phil Anselmo (Pantera). Over time, the band began to break down, partly due to label issues and partly due to Trent's lack of interest in the project and announced the band was dead in 2004.
Relationship to Puscifer and A Perfect Circle
Only one Tapeworm song was ever released to the public, "Vacant", which was performed live by A Perfect Circle on several occasions and eventually became "Passive" on their last full length release eMOTIVE. The band's live performance of the track before it's release has also been attributed to the demise of Tapeworm. It has also been rumored that the tracks released by Maynard's Puscifer side-project are actually renamed and reworked versions of the original Tapeworm tracks.
