Radiohead’s first show in Argentina in nine years experienced a slight hiccup when a crowd barrier malfunctioned at the Tecopolis festival in Villa Martelli. The band was performing “The Gloaming” when the barrier disaster struck and while concert security frantically tried to fix the issue; Radiohead frontman Thom Yorke seized the opportunity by gracing the crowd with a continued a capella performance of the song.

The song is from the classic and beloved 2003 album Hail to the Thief, the band’s sixth full length album. While “The Gloaming” was not a single from the record it quickly became a fan favorite during the band’s live performances.

In February, Radiohead announced a new batch of summer tour dates in North America after their current South American tour has concluded. The North American tour starts in Chicago and will hit cities such as New York, Toronto, Montreal and will end in Philadelphia.
