I haven't been to many concerts lately but a few good shows come to mind.
Jerry Garcia Band in Milwaukee in 90 or 91.
Cowboy Junkies in Bloomington,IN with about 50 people in 88.
Black Flag with Henry Rollins while in high school in Detroit. That show was amazing. Henry kicked some dude in the face who was in the front of the pit.
Clifton Chenier (spelling ?) at Summerfest in Milwaukee in 89.
Pearl Jam at Magnuson in 92.
