IMO, the Who are the only rock band with possibly the Pink Floyd with Roger Waters leading the charge, could sell millions of records, set world wide attendance records, and still be on the cutting edge of good solid song writing and great visual effects at live shows, with the Who's Pete Townsend going insane and destroying his guitar like a madman and the late Kieth Moon blowing up his drum set with hidden explosives on national TV, for good measure. Those guys could do that and be great rock bands who made classic records time and time again, it would be hard for any other band to do that these days because of the sensitivity of corporatism in music these days. It was controversial in the late 60's and 70's and 80's, it is probably more so these days in comparison.
