Fred Armisen is known for his spot-on comedic rhythm — but he keeps his musical rhythm somewhat under wraps. A peek into the Armisen personal history record, however, reveals he was a drummer in a Chicago punk band called Trenchmouth for eight years and a Blue Man Group drummer for two years. This week, though, on Jimmy Fallon’s show, the SNL and Portlandia comedian found himself in the hot seat, in the midst of a drum-off with The Roots drummer Questlove. And with our uneducated ears, we’d be hard-pressed to call a clear winner on this one.
