Overall I'd say Summerfest is kind of a bust this year and isn't even receiving much mention in articles about summer music festivals, but Bob Mould performing Copper Blue in its entirety would definitely be worth the price of admission.
That is, unless he loses his voice and random members of the audience sing the album for him.
July 3rd, 10pm. Shit, in the Leinenkugel's tent, to boot. They're really trying to rope me into this one.
