Your first concert was to see who and when?

I saw local bands like MC5, Iguanas (Iggy Pop's first band, my sister dating bass player), Sunday Funnies, Mitch Ryder, others I'm forgetting. This Ann Arbor, junior, high school days, lots of free concerts in the area. First paid big venue concert was Alice Cooper at Cobo Arena, Detroit, friend's mother transported us and attended concert. 

Led Zeppelin launching second album at Montreux casino spring 1970.

Led Zeppelin, MC5 and Johnny Winter 69 or 70 Boston Garden

RUSH in Toronto around 1983, Great show.

BTW - for you folks that mentioned Led Zeppelin, check out the BECOMING LED ZEPPELIN on Netflix. Zep is my fav band but after seeing that documentary they moved up to another level.

Mothers of Invention/Country Joe and the Fish/Ten Years After/Buddy Miles Express at Baltimore Civic Center on Apr 27, 1969.....
