The alt-rock gods of 1991 got all mixed up Saturday at Flea’s benefit for the Silverlake Conservatory Of Music. To close out their 11-song set, the Red Hot Chili Peppers did part of Nirvana’s era-defining “Smells Like Teen Spirit.” Guitarist John Frusciante, who has covered the song solo before, handled lead vocals on the chorus. He also did a solo run through the Ramones’ “I Remember You,” which he’s been doing during on tour during RHCP’s sets. Watch him lead the band through Nirvana’s signature song below.
