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.
