Multiple sound cuts forced rock band Radiohead to walk off Coachella's main stage twice.
The sound glitches began only three songs into the band's set, but grew much worse during "15 Step" cutting out the final two minutes of the track, reported Variety.
The band, composed of Thom Yorke, Jonny Greenwood, Ed O'Brien, Colin Greenwood and Phil Selway, then left the stage, only to return and have the same problem recur when they started performing "Let Down".
They eventually returned, but even the frontman Yorke seemed uncertain of the rest of the night.
"Can you actually hear me. I'd like to tell a joke to lighten the mood. But we're Radiohead so f- it," he said.
