Best concert you've attended

The Ramones, October 13, 1979, at Cahn Auditorium, Northwestern University.  really powerful performance, no sitting allowed.  I even remember the contrasting dance moves of a gay couple a couple rows in front of me: the tall guy was smooth, the short guy just pogoed.  

Muddy Waters, May 23, 1981, outdoors on the lakefront campus, Northwestern University.  This was one of his last headlining performances, he died less than two years later.  I had gotten into the Chicago blues scene starting my freshmen year, 1978, seeing people like Son Seals, Koko Taylor, Mighty Joe Young, and of course Buddy Guy at various Chicago blues joints.  But to see Muddy Waters himself!  His health was declining, so he never got off the stool, but it was electrifying.

Stanley Clarke, August 2015, at Blues Alley in DC.  He played with a 16-year old pianist from Georgia (the country), and an 18 year old drummer from Texas.  We had the table next to the stage, about 3 feet from Stanley.  They cooked.  This was two years after my oldest son committed suicide.  I was just coming out of the darkest period of my life, and seeing live music with friends helped me find happiness again.  

Woodstock 1969

Sigur Ros, Chicago 2022 I think.

Pink Floyd, Chapel Hill, NC around 1987

2 very different concerts:

Igor Stravinsky conducting the Philadelphia Orchestra in Persephone, Hill Auditorium, University of Michigan Ann Arbor, May 3, 1964

The Righteous  Brothers and the Shirelles, at corporate meeting in suburban Chicago, approx. 1985

@tomcarr At 16, my first concert was The Cure at Dodger Stadium in 1989.  That was the first time I had ever smelled weed.   I had no idea what it was, had to ask my friend's older sister.  Of course, she knew and she explained to me why I and my friend felt so sleepy.
