Caspa @ Glasgow School of Art, 24 May

There's no time to rest your dancing feet. After a bass-ridden two months, West London's dubstep giant Caspa rounds off the killer May line-up from Glasgow's foremost purveyors of bass, Mixed Bizness. Following Thunderheist and Ghostface Killah, Caspa's Glasgow debut promises pure dubstep beats and grime-y treats. His latest album, Everybody's Talking, No-one's Listening - which had special guests Skream and Benga dropping in on the launch at Fabric last month - has reignited his fans, building on the much-adored 2007 FabricLive mix with dubstep playmate Rusko. Caspa doesn't just deliver dubstep: he'll hit you with layers of grime and dub, decorating a relentless bassline with with trance-inspired melodic vocals that push the music onwards. This is dubstep for the dancefloor, and you know resident Benny Boom (Solid Steel) and Subcity's Djamba will honour it with their enviable dub and hiphop collection. Get your dub well and truly on.
