I was at this Mookie Blaylock (Pearl Jam) show
and Alice In Chains was headlining it before their first big tour (opening for Van Halen). It was 1990 and the only time I saw either band. Pearl Jam's first record wasn't out yet but there was still considerable interest because they were the new incarnation of Mother Love Bone.
I'm glad I got to see Nirvana twice.
Wish I could've seen The Beatles and Led Zep... but I'm not old enough.
