They're OK. Going to be at bonnaroo. Can't go this year. :(

Coachella has an even better lineup, imho. Kinda
at festivals. I dig them, but too many bands I like just do festivals and don't tour anymore over the summer.
I'd definitely agree that Coachella looks better. Bonnaroo is just easier to get to, and in the summer. Rothbury is close to my house in Michigan, maybe I can pick up Mr. and Mrs. Dave at the airport and take them.

Festivals are kind of a mixed bag...the sound is pretty sh*tty, but you get to see an unbelievable amount of good stuff for the money. I mean, I probably saw 10-15 bands that I'd pay 20 or 30 bucks to see in KC in addition to a bunch of good bands that I probably wouldn't pay to see in a normal setting.
