Diplo @ Cabaret Voltaire, 21 May

The reason everyone compares M.I.A. and Santigold (nee Santogold) is Wesley Pentz, aka Diplo, producer and one-time beau of the former, producer and remixer of the latter. He's an unstoppable record collector, a musical anthropologist who knows everything worth knowing about dub, reggae, hip-hop and electro, and has no qualms about moving between the genres at pace. Even better than Santogold's debut album was Diplo's mixtape with her, Top Ranking, which you can and should download for free if you've any doubts about the prospective merits of this night - and check out that bargain ticket price too.
