Karen O 'Indian Summer' (the Doors cover) / 'High and Dry' (Radiohead cover)
Stepping away from her role as the Yeah Yeah Yeahs' leading lady, Karen O has been touring the UK in support of her latest solo effort Crush Songs.

Over the weekend, she charmed the audience at London's Bush Hall when she delivered a pair of unexpected covers during her set. Backed by Holly Miranda and Moses Sumney, the trio "ooh"-ed their way through the Doors' 1970 classic "Indian Summer."

Before the end of the evening, Karen O and her band also took on Radiohead's "High and Dry," with Miranda leading the crowd through a sing-along rendition of The Bends tune. Crush Songs is out now via Julian Casablancas' Cult Records.
