9. Dave Matthews Band
After a main-set-closing medley of "Time Bomb" and the well-aged "Two Step," Matthews emerged alone for an encore, half-apologizing to the audience for the downer before picking his way through a spot-on take on Neil Young's "Needle and the Damage Done." But then the band dove headlong into a typically exceptional workout on "All Along the Watchtower," which featured enough Carter Beauford and Tim Reynolds deliciousness to serve as the 2010 festival's last song. In doing so, DMB (like Phish before them) demonstrated the Bonnaroo headliner's creed: Sometimes, at the end of a long day or three, the people just want a good cover song.
