Your First Concert was.....

I saw Steppenwolf at The Grande Ballroom in 1968 and the drummer was so high he fell backwards off his stool. As he fell he was still swinging his sticks.

Saw Hendrix in '68 at, I'm pretty sure, Detroit's Masonic Auditorium. His amps kept picking up a talk show from a local AM station, WJR. I thought it was part of the show.

Those "large, immobile systems" are what allows us to hear actual music as opposed to mobile MP3s and earbuds creating constant meaningless white noise.

And by the way, concerts from Mozart's time (and long before) and through today are large, immobile systems for listening to music. I think I can say with confidence that 40 years from now no one will be releasing Maroon 5, 50 Cent, or Fiest compilations, let along ones that hit the top ten list.
