Sorry, I missed this conversation.
I once went to a Fugazi show and both L7 and Pearl Jam opened, but I would have to say one of my all-time my favorite shows was October '91, Pearl Jam, Alice in Chains, and Temple of the Dog all opening for Soundgarden at the Palladium in Hollywood (not my fave PJ show, but ALL TIME shows).
As headliners, RATM opening for Pearl Jam right before my high school graduation was also pretty awesome, and seeing both of them again at Lollapalooza that summer was pretty good too.
But I would say my all time favorite PJ show was the Empire Polo Grounds (now commonly referred to as Coachella) in '93. Did the overnight, all of it, before it was cool, and even though the crowd pissed off Eddie with some shoe throwing and they played Sonic Reducer behind the stacks, they crushed a solid playlist and capped it with a Baba O'Riley ending:
