Radiohead singer Thom Yorke opens Venice exhibition with Stanley Donwood.

Radiohead singer Thom Yorke and artist Stanley Donwood have opened their first-ever exhibition outside the UK at Castello 2432 in Venice. Titled "No Go Elevator (Not Without No Keycard)," the show features new ink drawings and a large-scale painting created in London earlier this year, timed to the start of the 61st Venice Biennale. The exhibition runs through June 7.
