See now, this is the problem with booking the nostalgia ticket - they start backing out. We blame the Alzheimer’s, mostly. Sadly, Sonic Youth appears to be headed to the trashheap of the ACL lineup cancelations, a rumor that’s been bubbling all week and that the Chronicle just reaffirmed with news that their ACL taping has been canned. It seems that ACL is beginning to look like high school not only in its aesthetic this year, but also its drop out rate. They should get Lil Wayne on that shit! Anyway, the reason for the pullout is apparently that Lee Renaldo broke his wrist, which sucks, but we suspect this is really just the catty kind of shit that happens when start hanging around with those damn Gossip Girls. Sonic Youth is currently still scheduled to play Sunday night from 7-8, right before Pearl Jam’s headlining set and opposite Dan Auerbach and Girl Talk. C3 refuses to confirm, because they’re like the damn New England Patriots when it comes to announcing status updates. We’ll keep you posted.
