King Sunny Ade in Camden

Nigerian juju musuic monarch King Sunny Ade plays Wiggins Park in Camden on Tuesday night. Ade, whose  2000 album, Seven Degrees North, has just been reissued, doesn't tour as frequently as he did back in the 1980s, when, along with fellow Nigerian Fela Kuti, he was at the forefront of exposing Western ears to intoxicating Afrobeat jams. So this is a rare treat, and besides, it's free.
