In 1971, facing tax problems and an uncertain future, the Rolling Stones decamped to Villa Nellcôte on the Côte d’Azur, where they partied with various celebrities, musicians, girlfriends, wives, kids, animals, drug-dealers and hangers-on for several hedonistic months. Recording in the damp, labyrinthine basement with a mobile studio parked outside and musicians seemingly turning up at random, they somehow produced Exile on Main St, a rough-hewn, sprawling, eclectic, 18-song double album that is widely regarded as their creative peak. Here, as it turns 50, stars salute its enduring greatness.
