Dr Lektroluv!!
(saw him spin in Rotterdam...just a crazy, fun DJ, and he ended with Trentmoller's remix of Royksopp's "What Else is There", which was one of my favorite club experiences ever)
Not going, but i'd also dig seeing: MSTRKRFT, Justice, Adam Beyer; Trentmoller, and i guess Klaxons (to see what they're all about).
Looks like a fine lineup!
