Let’s see, some of my favorite shows …

The Urban Guerrillas at the UW-Eau Claire
The Replacements/Paul Westerberg - various places
(I regret missing Husker Du though I’ve seen the Grant Hart & Bob Mould since)
Patti Smith
X - several times
Hole - fairly shortly after Cobain’s suicide. She was a train wreck but the show was pretty good anyway.
U2 - played Camp Randal. Amazing hearing 50,000 people singing “Pride”.
Concrete Blond

My best friend got tickets to the Who in Chicago when the Clash opened for them. Unfortunately, I spend _that_ night in Basic Training O_o

Most of the best of the rest were small local bands.
