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

I have seen great symphonies, Chicago, Moscow, Boston and others including some smaller cities performers that were quite good, Madison, Wi, Milwaukee and some other Midwest cities.  Actually did a bike trail with the first chair Cello player from the Chicago Symphony and his girlfriend from the singers and they stayed at my home and I made a very good meal for them....with a excellent Bordeaux...and this made for a great memory. 

As far as Jazz and Pop, the list is long and I am fortunate to have had the opportunity to see these.
James Taylor
Jackson Browne (several times) the best was "Running on Empty" tour. 
Little River Band 
Heart
Chicago
B.S.and T. 
Nancy Wilson
Woody Allen, Jazz bar in NYC
Harold Land (just great)
Julia Fordham (a few times)
Gene Pitney (I was amazed at how good he was and how much he sounded just like his recordings)
Hall & Oats
Peter whatever his name was, Switched On Bach
Joni Mitchell 
Diana Krall, a few times, and once with Elvis.
Wynton Marsalis
and more than are coming to mind...
 
I wish I could have seen, Chet Baker, Paul Desmond, Ella, Dinah Washington, Blue Mitchell, Art Farmer, Clifford Brown, early Rosie Clooney, and many more that were so great in the 40s through the early 70s.

And I am a bit sorry to say, I have seen more than I have listed and cannot instantly recall them....but all part of being an old fart, my sons call it O.F.S., Old Fart Syndrome.

It would be good to hear from members about your live music experiences.
