I like some of the responses. I went to band and orchestra concerts from a very early age. First rock concert I saw where the band's name was on the ticket was with my parents. It was a band called Chase, a one hit wonder and it would have been very early 1970's. They were similar to Blood Sweat and Tears and Chicago. First concert on my own with tickets (and not chaperoned by school) was Spyro Gyra in 1980.
