Best concert you've attended

As far as the overall experience, Muse. But my favorite show was RUSH. I scored 4th row center trying the day of show ticket thing and I caught a t-chirt Geddy tossed out from a dryer. 

Pink Floyd, Yes, The Who, Rush, Deep Purple quickly come to mind.

Grateful Dead 7/2/88 ..my admission to another dimension 

Saw Phish at Sphere in 2024 hard to not include that due to the venue 

There’s been a number of them, but probably it was The Moody Blues tour for the Octave album. They were good but the opening act was relatively unknown at the time, Stevie Ray Vaughan and Double Trouble. 
 

I have many others but thought I’d keep down to one best.

I answered this question on a similar post last year in more detail but as far as bigger concerts go, one that stands out was the 1984 Roger Waters Pros and Cons of Hitchhiking tour in London. Great crowd and vibe. Saw him again years later in Boston and the crowd was less amicable.
