The most awesome performance I've seen was My Morning Jacket in Nashville back in August. Watching a video wouldn't do the performance justice. Anyway, they were in the middle of a jam out of "War Begun" (the venue we were at was across the river from LP Field, where the Titans play--- and it's outside as well) and all the sudden fireworks from the Titans game started going off, most amazing thing ever. Such a great night.
