Of all the guests Jimmy Fallon had on his show yesterday night — which included Penelope Cruz, Levar Burton and Kate Upton (The Roots not included), obviously the best was the Robert Glasper Experiment. The maestros of jazz, blues and hip hop played their classic rendition of Nirvana's "Smells Like Teen Spirit", off their latest album Black Radio. Casey Benjamin on vocoder and Chris Dave obliterating the drumbeat made this is a performance worth revisiting.
