Galleries across London will show contemporary art from across the world this weekend – for free. Here are our top picks
Lonnie Holley grew up in 1950s Alabama scratching a living from selling people’s castoffs, and the self-taught artist’s intuitive, compulsively made assemblages still give new life to unwanted flotsam. Though his art is rooted in the deep south, it is Suffolk’s former military test site, Orford Ness – the basis for a new song cycle commissioned by public art trailblazers Artangel – that informs his latest sculptures and paintings.
Edel Assanti, from 13 May to 2 July.
