Best Concert/Worst Concert you've ever been to...........

[chasfh]

Sonic’s Rendezvous played a dance at my high school in, I wanna say, 1977. Pretty unforgettable, in that I still remember it.

Worst... There was a series of concerts on campus in college one day, and I will never forget how bad I Am Robot was (fronted by Edward Sharpe)

I hope this is the right thread.  Rush is worth seeing.
