Haven't heard of these guys...Black Sabbath cover band?
Discussion
Yep, exactly. Pretty big names though:
ZAKK SABBATH is the Black Sabbath all-star cover band featuring vocalist/guitarist Zakk Wylde (Ozzy Osbourne, Black Label Society), bassist Blasko (Ozzy Osbourne, Rob Zombie), and drummer Joey Castillo (Danzig, Queens Of The Stone Age)
