I think it is about stage presence as well as content, though, even for DJs. I mean people automatically look to the direction the sound is coming from, yeah? It's human nature. That's like going to check out a rock band, paying your $ but never looking at them. At that point you might as well put in a mix CD or do an ISDN concert like FSOL used to do, or put Mills on the flyer and play a copy of "The Exhibitionist"
Just my .02
Oh, Ben Sims is a top bloke, very down-to-earth and I'd have Finke over here in a heartbeat if the US scene wasn't so shitty
