Not to be a total ass- but I am one; There already has been a number of thrash supergroups: Megadeth, Slayer, Metallica, Testament, Dark Angel, Kreator, Sepultura. Each one of these bands were comprised of some of the best musicians the thrash scene ever had. With the exception of Clemente the early drummer of testament, Tom Araya's non-existent bass, Mustaines nasal voice( which i kinda of like), lars ulrichs ego, and the horrible production found on Dark Angel's albums, each one of these bands were a supergroup. Hell Testament and Slayer are still going strong, and Kreator put out a damn good album a few years ago.
