The Knowledge Arts Festival

East London's annual arts festival returns for two days this September, featuring a free street party at Derbyshire Street Pocket Park (Sat; 11am-4pm), a chance to see artists' wacky Fun Palace pitches for Oxford House's Oh! Theatre (Fri; 6pm) and Tom Adams's 'Still Score' (Fri; 7.30pm), a musical/comedic performance that tells the story of strangers in pictures that Adams acquired when he bought a slide projector containing 500 slides off Ebay.
