Live music you have attended that left impact....perhaps better than you expected.

I've done the rock thing since the early 1970's. Have been to more concerts then I can remember.
One that I do recall was skipping out of high school with some friends, heading to Central Park to see Jefferson Airplane/Starship ( whatever they called themselves at that point) with 200k other people. These days I think they suck musically but it was an awesome event. NYC was a great place.
In the 70's in NY you could go out any night of the week and find great music. Every bar had a band. What I remember most are the jazz players. Dizzy at the Village Gate. Buddy Rich and his Allstars at a tiny venue in Hartsdale, NY. - Syncopation was the name of the place
Then in 1976 or 77? we had tickets to see John Mayall in the same little place. We started to drive there and realized all the lights were out....yep the big east coast blackout. We arrived and were told not to leave. Some pickup trucks arrived with generators and parked out back. They played all night long and we walked out when the sun was shining.
Seen Dylan more times then I can count but I remember most was after the old United Palace (Broadway and 170th St?) reopened. Awesome Concert. Awesome venue. Seen many concerts there. And his annual concerts at the Beacon...yep been to many of them
There was (and still is) The Blue Note Cafe in the west village, and yea the Village Vanguard!!!!
Then there was a period in my life where I would just buy tickets to Lincoln center and go listen to  the philharmonic orchestra. I was staving off NY burn out at an early age. Often I would take my than young daughter. We'd arrive, I'd close my eyes and in two hours I am sure I traveled a few million miles and back again. Alice Tully Hall....Really Great music...mostly I remember piano greats.
The Newport Jazz Festival in Saratoga was an annual and always an epic event.
The last concert I attended pre-covid was The Who in Madison Square Garden with my now 32 year old kid. The violin player is one of her clients.
Of course there was always Zappa on Halloween night
Many many more that I'm leaving out.
What I don't understand: where did the live music go? none of the local places have live music anymore

Thank you for your posts.  All of you have seen people I would like to have seen.  Sweet Basil's and The Blue Note in NYC were simply great evenings with great music and friends.

Perhaps the oddest musical experience I ever had was when I was in the Air Force and went to the "club" art a remote base in the middle of nowhere and a group showed up with a pretty blond and brunette that turned out to be ABBA....don't know what they were calling themselves at the time.  Also I was on vacation and one evening at a nice "yacht club/bar/supper club" this young grey haired guy started doing a comedy routine,...it was Steve Martin in his early days.  Oddly later I was at MOMA in NYC and in a room with a huge Jackson Pollock I was backing up to get a better look and backed into someone....turned out to be Steve Martin.  
So many interesting experiences in my life have very much been unplanned surprises, like when racing at Road America and having contact with Paul Newman.  

Went to hear Jose Feliciano with a friend several years ago at a small venue.  I really wasn't too interested, but we ended knowing the door man, got great seats, and proceeded to be blown away by how good Jose and his band were.  Jose is blind, and so was his piano player. To say the band was "tight" is an understatement.   He can play a lot more than Feliz Navidad!  They even played some Hendrix.  One of the best shows I've ever attended.

I’ve seen a bunch of superb live musical performances in my day. The ones, though, that were truly transcendent and altered my taste were (Speak memory!) are...

Springsteen at the Inglewood Forum.
The Berlin Phil with Von Karajan at (where?) the Ambassador Auditorium.
Television at the Whiskey.
Bizet’s Carmen at the Dorothy Chandler Pavilion

Took my daughter to see Harry Styles (pre COVID) was floored the guy is fantastic and has a great band.

We flew down to Dallas (see my son and daughter-in-law) and went to Harry Styles show there. Jenny Lewis opened for him and was wonderful.
Great performer just to many screaming girls lol.
