Friday night Coachella headliner Radiohead faced major sound system failure during their closing performance, leaving fans who paid hundreds of dollars to watch the U.K. band perform on a soundless main stage.

The technical difficulties began during A Moon Shaped Pool's "Ful Stop," with sound dropping while Radiohead continued their performance, unaware of the issue. The sound returned for their next live performance of "15 Step," but then it dropped out again -- and again for "Let Down."

The jarring tech issues prompted Thom Yorke walk off stage, but then he returned to address fans: "Can you actually hear me now? I’d love to tell you a joke, lighten the mood, something like that. But this is Radiohead."

Radiohead went on to perform other numbers from A Moon Shaped Pool including "Burn the Witch" and oldies like "Karma Police." A Coachella spokesperson didn’t respond to Los Angeles Times' request for comment about the incident.
