Joe Gideon And The Shark @ Cabaret Voltaire, 23 Mar

They may have an irritating tendency to talk about themselves in the third person, The Shark is also known as Viva, and they used to be in Bikini Atoll, but don’t let all that put you off. Brother-sister duo Joe Gideon And The Shark have created their own dark, dramatic world, and their surreal take on ramshackle blues benefits from a little pretension: after all, if they don’t believe in it, why should you? They don’t, however, seem to have problems converting fans, and their gigs are reported to send even the fiercest sceptics into fits of dancing, arms-a-flailing. You've been warned. [Heather Crumley]
