Yes they did.
Right before them, saw Band of Horses. Good show. Other acts during the weekend:
Friday:
Bobby Bare, Jr.--first few songs meandered around, then gave an inspired performance.
Ryan Bingham--country/rock--good sound.
Alejandro Escovedo--not ready for prime time.
Saturday:
Robert Earl Keen--the road goes on forever, the party never ends. Great show.
John Fogerty--tight sound. He hit all of the CCR stuff.
Plant and Krauss--couldn't believe how much Plant sounded just like Plant. Great band behind them.
Note: was told that the Black Keys was an outstanding show. Missed it.
Sunday:
Silversun Pickups: couldn't get into them.
Shooter Jennings: same.
White Denim: same.
Band of Horses and Foo Fighters--great acts.
Kevin Fowler: heard he put on a great show.
Overall, ACL did not live up to last year and could use a little more star power, imho. The beer selection was the same as last year: Heineken and Lone Star. Drank a lot of it, but somebody needs to get Spoetzl to go strong on the ACL bid for next year. Also, the port a can situation is awful. With all the engineering talent in Austin, can't somebody figure out a way to construct Oktoberfest style pee troughs, thereby freeing up the port a cans for the ladies? It would speed up things for everyone.
