According to Pitchfork, Wavves self-destructed last night on stage at the Primavera Sound Festival in Barcelona, Spain. The following is a brief except from
this article.
At 3:00 a.m. sharp, having dodged their share of bottles and even a shoe (neither Nathan nor Ryan was hit, although Nathan likely made impact with some unlucky attendee upon forcefully returning the latter object back to the crowd), the show mercifully came to a screeching halt: Ryan ran offstage, throwing his drumsticks at Nathan. Infuriated, Nathan screamed into the mic, "Come back here, motherfucker, we're not done yet!" Immediately, stage crew appeared, breaking down Ryan's kit. "Fuck!" Nathan shouted, "Stop doing that!" They didn't, so Nathan decided the show must go on. Helplessly, he strummed his guitar again, clearly intent on playing another song. But as he stepped back to the mic, he realized it had been cut. As the crowd booed, the house lights came up, and a defeated Nathan Williams threw his hands up and left, along with the few remaining attendees.
Wavves then canceled the first show following the performance. While the venue is claiming that the vocalist is experiencing health issues, Pitchfork is reporting that the band missed their flight from Barcelona to Lisbon.
