Best concert you've attended

Jimi Hendrix Boston Gardens, The summer of 1970

Missa Solemnis - LA Phil, Dudamel, 200+ voices WDCH. Subscriber but upgraded to third row center. I will, and most will, never see the likes again. 
Stunning. Like most respondents - a variety of rock concerts over the years but for shear mind blowing sound - unamplified or manuipulated it was trancendent - as the composer wished it to be.

The Jackson Five - Ft. Wayne, IN  Memorial Coliseum 1971

Yes - Ft. Wayne, IN  Memorial Coliseum 1972

Now this was that transition year from an 8th grader to a 9th grade freshman in highschool.  A massive jump in perspectives, to say the least.

Santana - Ft. Wayne, IN  Memorial Coliseum 1973

And this was all general seating, meaning we sat cross legged on the concrete concert floor and boogied with the best of them.

I have been to many shows in my life going back from the mid 70's through the 80's and so on I could list a ton of them but will not. Short and simple.. I just saw David Byrne at a small 2 to 3K capacity venue and I will have to say it was nothing short of amazing. It was like a moving Art presentation. Look him up some time " Who is the Sky " Tour.

Of the more recent concerts I really enjoyed was Dwight Yoakum and two bands that opened for him.  I don’t recall the name of the first band, but the second band was a Tex-mex band, the Mavericks.  If you like that style of music, I recommend seeing them.  I went to hear Dwight but actually enjoyed the Mavericks even more.
