Radiohead’s headlining set at Coachella last night was marred by numerous technical difficulties. The sound cut out three songs into their performance — during “Ful Stop,” funnily enough — and then cut out again in the middle of “15 Step.” After a brief intermission to deal with the audio issues, Radiohead returned to the stage to continue the show, but they only managed to get through one song before the sound once again cut out during “Let Down.” The band didn’t seem too fazed, though, with Thom Yorke cracking jokes about aliens being responsible, and after another intermission, the rest of the show went off without a hitch. The fans who stuck around were treated to performances of classics like “Creep,” “Karma Police,” and “Paranoid Android.” Watch some footage from the troubled set below.
