The biggest treat of the weekend is a rare appearance by King Sunny Ade, the Nigerian master of juju music, a jubilant mix of Western pop and traditional Nigerian guitar styles that inspires dancing from audiences all over the world.

He'll play the Blue Horizon, a boxing room perfectly set up for an authentic Nigerian party and the audience-participation custom of tipping, where the audience offers money to the performer, who responds with song (9 p.m. Saturday, Mar. 26, 1314 N. Broad St., 215-763-0500, $29.95, www.ksa2005.com).
