[Rez]

it was pretty crappy too.

most of these are reaching a fair bit, but thats the point, i think:

jackson and his computer band with missy elliot with daft punk
lightning bolt with beck
buffalo daughter with underworld
Mu with aphex twin
Air with The Books
death in vegas with gorillaz
prince and trent reznor (rongi just hit on genius for that one)
Pan Sonic with M83 (probably impossible)
