Pearl jam, the guy was so drunk he kept falling over. I was backstage. He downed 2/3-3/4 a bottle of whiskey during the show...well some was already gone when they started. Maybe sober?
Nirvana holds a special place for me. I was young and wild. I discovered belly through them, also awesome:) I love when bands have good bands opening.
Soundgarden could play well, they were very good live. The bands they've split up into, also really good live.
Alice in chains. Totally different vibe than the others, I think.
STP I saw after their prime and I don't really remember the show, which isn't usually a great sign. Honestly I walked away, because the people I went with wanted to.
I cant pick, because the shows are so different. I like them all...well all but pearl jam, were ok to great live. Musicians have off nights, but watching pearl jam was like watching a train wreck:(
Nirvana/Alice in chains, soundgarden, stp, pearl jam:)...in that order I suppose. I'd probably put the first 3 way up high on the list, stp in the middle to top, and pearl jam way down at the bottom.
