I fully agree with what he said.
edit: wait, this argument already happened. I will however still agree with him.
I mean, you could tell the average fanbase at Coachella. I was able to get close spots for acts like Echo & the Bunnymen and PiL. After Infected Mushroom, the Sahara tent practically emptied out for Orbital, and it was teens running out, and the older generation running in. Same for Plastikman. Some older DJs, most notably Bentley, played to smaller crowds, while the dupstep DJs (surprised to see this stuff so popular) were packing the tent.
So yeah, if they booked great acts that weren't the hype of the moment by Pitchfork or whatever blog hipsters are reading today, then I do believe that the fanbase would be different.
