cavalera/ex-sepultura
Maybe you're gonna kill me for this, but when I saw Sepultura in 2011 on the Thrashfest Classics tour (when they only played songs from Beneath the Remains, Arise and Chaos AD), Eloy Casagrande wasn't inferior to Igor Cavalera in any way... Plus cosidering the fact that he is younger than the songs he plays, his drumming was simply amazing!
But now to the actual question:
(1) Steve "Doc" Wacholz (Ex-Savatage)
(2) Ingo Schwichtenberg (Ex-Helloween)
(3) Thomas "The Omen" Stauch (Ex-Blind Guardian)
Seems I like former drummers more than the recent/last ones....
