Festival No.6 at Tate Britain

Festival No.6 is putting away its tent poles and travelling from Portmeirion to Tate Britain for a one-night music and culture extravaganza. It's set to be a Tate Lates like no other: a mini-fest with a headline performance from British indie band Blossoms, poetry from John Cooper Clarke, comedy from Sarah Pascoe, and pop-up theatre shows across the gallery. The £69 ticket price includes after-hours access to the David Hockney retrospective, the most over-subscribed art show in town.
