You and I both got dragged along to some concerts in our childhood. Some good ones were Dave Brubeck, and Gilbert & Sullivan operas produced in college towns. Any number of orchestras.
By the time I got to late High School and College, I was volunteering at the Penn State Jazz Club to be stage crew and/or ushers at concerts, and stage/help/whatever at some of Penn State’s outdoor concerts.
First things I paid for? Maybe Frank Zappa in the Apostrophe tour. Or King Crimson Lark’s Tongue in Aspic. Jethro Tull - in the Aqualung/Thick as a Brick period. John Mayall and the Bluesbreakers on tour. Springsteen right after Wild, Innocent and the E Street Shuffle.
If you really remember the order of all of that stuff, you probably weren’t enjoying the time enough.
