Olivier Desmet (fantastic taste in house, head of amenti music label)
Fred Everything
Inland Knights (listening to a live set right now and its just FIRE)
Farina would be on this list, but I was fortunate enough to shake his hand after a show, so sort of met him already.
I'd love to collaborate with Lorin from Bassnectar. He not only plays music, he controls the crowd with that ridiculous WOMP. %) As a Matter of fact...I have Backpack Rehab on blast.
Lorin from Bassnectar, Joel Zimmerman so I can punch him in the face, Rusko, Skream, Michael Travis and Jason Hann even though they are not DJ's (Jason goes by Prophet Massive and plays DJ sets though), Simon Posford, and Chemical Tom and Chemical Ed (Last but not least).
Simon Posford of course. and Psykovsky. Psykovsky would be an interesting character to talk to. I mean look at him during his dj sets. http://www.youtube.com/watch?v=SB7DnxJocqA He looks like he's going insane.
Sven Vath, any of the original chicago, new york, detroit djs, tiga would all be interesting to talk to, outside of that they are just people doing a job, and if you follow enough of them on twitter, most have enormous ego and are fairly self obsessed.
I'd like to meet any of the Hardcore guys like Mark Breeze, Luna C, Scott Brown, that sort of thing :D Maybe Simon Posford (Shpongle) or the guys behind Boards of Canada
