Wow, this sounds so middle-class and uncool but.....
INXS, The X Factor World Tour - The Coliseum, Portland Oregon, 29th March 1991. (I had to look up the date.)
I grew up where the nearest live music venue of any kind was 3+ hours' drive away so this was a Very Big Deal for a girl from my town to travel to. I was 22. Michael Hutchence prowled the stage and gangways like a panther. I had no idea a song could sound other than the recorded studio version. Utterly changed my life.
(I saw INXS again a few years later. Rubbish album, rubbish gig. I walked out halfway through. Not that this restores any street cred, of course.
