I'll echo Steve's comments on Artist Unknown - they have a great stage show, performing retro electro in Eyes Without A Face masks, climbing over speakers, playing drum machines like guitars whilst the computer sings along to Guns and Roses covers and stuff like that. I can remember that one of their cuts was called "Dance Like Spastics" which sort of sums up their sense of humour!
They had a 12" on Disko B last year called "Piper at the Gates of Detroit" which was much like their live stuff, and they had a 10" out about two months back which was filed in the drum and bass section... BABY DIDDY
