Yoko Ono

Much more than just a famous widow, Yoko Ono is a revered (and occasionally mocked) avant-garde artist with over 50 years' experience pushing musical, conceptual and visual boundaries. She returns to London to play two surprise sets at Dalston's improv and experimental music hub Cafe Oto, collaborating with Thurston Moore and Steve Shelley of Sonic Youth (March 22) and Nels Cline and Talvin Singh (March 25).
