D'Angelo made a surprise appearance last night at Bonnaroo during Questlove's "Superjam," his first performance in the U.S. in over a decade (he's performed in Europe a few times this year). Questlove introduced him by saying, "I've been waiting 12 years to say this -- ladies and gentlemen, D'Angelo!" The jam also featured veteran musicians like bassist Pino Palladino, percussionist Frank Knuckles, saxophonist Eric Leeds, and guitarist Jesse Johnson, who joined Questlove and D'Angelo in covering tracks like Funkadelic's "Hit It & Quit It," The Beatles' "She Came In Through The Bathroom Window," and Led Zeppelin's "What Is and What Should Never Be." 

No D'Angelo songs were played during the surprise set, but fans can expect to see him performing original material, old and new, at the Essence Music Festival in July and at Jay-Z's Made In America festival in September.
