I'm just back from Bonnaroo, and I nominate Radiohead, with Tom Petty and the Heartbreakers as a close second. They really surprised me, as I had never really given them much attention, but Petty's show was scorching, especially the brief set of songs that influenced them when they were yount, including the Yardbirds' "I'm a Man" and a fabulous version of "Oh Well" by the original Fleetwood Mac.
Radiohead was simply sublime.

Agree 100%. The festival was great, but the Radiohead 28 song setlist was absolutely incredible. It was like seeing The Beatles in '65 for me, except this time i could hear them, appreciate them, and oh, my oldest son was there to celebrate it with me. Great monents.
I also agree that the Petty show was more than I though it would be. When he went to "Oh Well" and nailed it, blues and all, I found a new appreciation. We sauntered inot the What Stage rather late for his show, stood way back by the mist tent, and still enjoyed it. Radiohead, well, we were MUCH closer.
