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

A little of topic, but even as a lifetime R&R fan I would like to have witnessed performance of some of the greatest Classical pieces by the masters.

Vivaldi,Hayden,Bach, Beethoven, Mozart....

Anything else seems insignificant. Seating accommodations and no A/C  was probably awful though. Wouldn't have to stress about the guy in front of me with the Iphone recording. Are there some of THESE guys here?

Good thinking...

After all - Mr. Peabody and Sherman did pay a visit to Beethoven.

Suitable clothing (wardrobe) would take a bit of doing, but it is doable.

DeKay

Iron Butterfly - Metamorphosis Saw them in '77 for $3 fantastic
Storyville   
Crack the Sky   
Keb Mo 
The Eagles pre Joe Walsh
Rossington Collins - Anywhere, Anytime, Anyplace LOVE Dale Krantz' vocals
Mylon LeFevre & Broken Heart. Great show and music
Larry Howard - Cornerstone Blues Jam   
Black Oak Arkansas - Raunch n Roll  Tommy Aldridge drum solo one of the best
Aerosmith - Get Your Wings
Too many more to list. obviously all the classic rockers, Zep, Sabbath, Butterfly, Hendrix, etc.

One more, is the time our band was playing a club in Charlotte in '79. We were the House Band. ZZ Top's pickers came in with 2 GORGEOUS women and sat up close to the band. Hard to mistake the beards. Anyway, the 2 girls got up to dance and they shook things that I didn't know would even shake. The band dropped the music instantly and picked it up again in a split second. It was as if someone had pulled the plug and quickly  put it back. It was among the funniest things I have ever seen  or had happen in my time playing. No one in the audience ever said anything about it but I heard it. BTW I have loved playing music live and listening live & recorded. I consider it a way of life, not a hobby.

Beatles at the Hollywood Bowl. My sister had a friend who had a very good seat.  She was supposedly hoarse for the next several days due to all her screaming.

The Doors at the Whiskey. 

I got to say, though, that I went to lot of legendary concerts when I was, ahem, a bit younger.

@tablejockey , I was wondering if anyone would go way back in time to catch some of all time great classical composers. So, congrats on being the first! (bravest?)
