If you've seen Whiplash [1], you know J.K. Simmons plays a pretty scary guy. He's been winning awards left and right for his performance as a jazz drum teacher, a character he brought back for his hosting gig on Saturday Night Live [2] this weekend.

Take a look, and check out D'Angelo's powerful performances [3] from the show.
