Your idea for a American Super-group.

This band would smoke...

Guitars: Zak Wylde, Dimebag Darrell
Bass:Less Claypool
Drums: Danny Carey
Vocals:Mike Patton


I can't see them agreeing on a musical direction though.
 
All star ghost band

Vocals: Paul Baloff (ex-Exodus) R.I.P
Bass: Roger Paterson (ex-Atheist) R.I.P
Guitars: Teemu Raimoranta (ex-Finntroll) R.I.P
Guitars: Euronymous (ex-Mayhem) R.I.P
Guitars: Criss Olivia (ex-Savatage) R.I.P
Drums: Steve MacDonald (ex-Gorguts) R.I.P

(Fuck the american thing, ghosts exist in infinity so time/space is no object!)
 
Mike Patton - Vocals
Devin Townsend - Guitars, Background Vox
Dimebag - Guitars
Les Claypool - Bass
Thomas Haake - Drums (have tio import him from Europe though)

This lineup would be indestructable ! It would rule !
 
As said before.. Testaments - The Gathering had god damn near the ultimate line-up.. But my allstar team would be:

Vocals - Phil Anselmo and Layne Staley
Guitars - James Murphy and John Petrucci
Bass - Les Claypool
Drums - Sean Reinert
