47. Dave Lombardo
Cuban-born speed demon Dave Lombardo earned the nickname "A.D.Dave" from his Slayer bandmates after effortlessly keeping the pace on breakneck ragers like "Angel of Death" – which tops out at 210 b.p.m. and includes one of the most awe-inspiring drum breaks in metal – and "War Ensemble," all while hinting at swinging Latin jazz. Inner-band tensions have forced him in and out of the band a couple of times (he's currently playing with Dead Cross), but those fluctuations have allowed him to test his mettle with art-metal experimenters Fantômas, renowned composer/provocateur John Zorn, trip-hop leader DJ Spooky and visual artist Matthew Barney. "He's a caffeine-head," Lombardo's former Slayer bandmate Kerry King once said. "He's always ampin'. He can't sit still."
