If you had access to a time machine, what concerts would you go back to see?


2020 was the first year of my adult life that I did not attend any concerts. I'm sure that I'm not alone in this unfortunate situation. So, this got me thinking about both the concerts that I "missed" (could've gone, but something went wrong) or concerts I "wished I'd had the chance to see."

Plus, I thought this would be a good bookend to the ongoing (and excellent) thread about "the worst concert you ever saw."

Led Zepplin, Little Feat(2) Kinks,
The Who, Neil Young, Bob Seger(3)
Early Fleetwood Mac(3) Deep Purple, Beach Boys, Springsteen, Early ZZ Top, Blue Oyster Cult, very early Alice Cooper, Amazing Rhythm Aces, Elton John, Wishbone Ash, Ink Spots, Freddy Cannon, Dillards, Brownsville Station...
fond memories from classical concerts as well... 
The Doors
Stevie Ray Vaughan
Linda Ronstadt (before the politics)
Elvis in Vegas

that's what comes to mind, too many to list.

This is a broad topic. My joke choice would be Stones at Altamont ’69. But here goes,

Mozarts subscription concerts in Vienna mid 1780’s where he introduced all those beautiful piano concertos and the premier of any of the Mozart/Daponte operas.

Any complete or nearly complete performance of Les Troyens during Berlioz’s lifetime.

The premier of Wagners Tristan und Isolde and/or Parsifal.

A Gilbert and Sullivan Operetta at the Savoy 1870-80’s preferably the Mikado.

On a more modern note,

The Beatles, Hendrix (on a not so sloppy night), Jeff Beck group w/Rod ’68?, The Who circa 1970 (probably Isle of Wight), Pink Floyd circa DSOTM, Zappa 73-74 with Roxy band and/or The MOI at the Garrick theatre ’67, Deep Purple at one of the Japan shows ’72.

Miles Davis, either great Quintet w/either Coltrane or Shorter (sorry Coleman), Louis Armstrong Hot Fives/Sevens and Duke Ellington (Blanton-Webster) circa 1940-42.

You would be nuts if you did not choose one, any one, with Bach at the helm.
I think some posters are not keeping with the original intent of this thread (unless I misunderstood the OP's intention). I thought that we were supposed to mention concerts that we had once actually attended and would like to relive, not concerts that we wish we had attended. It seems that we're getting a lot of that.
