Damn too many to list. I was a teenager during the mid/late 70's and living within an hour of Columbus and Dayton and 1 1/2 of Cincy (Ohio of course). Well over 100 concerts. I enjoyed all, but a few are classics. Led Zep., The Who, UFO (one of my favorites), Black Sabbath (Ozzy and Dio versions), BOC, actually I saw Blue Oyster Cult with Sabbath during the Black and Blue tour. Rainbow (Dio singing), Blackmore is the shitzzz. Cant forget my main man Alice Cooper !!! Seen him over 10 times. Never gets old. Of course there are the good concerts too. Kinks, Romantics, Journey, Kiss, Rick Derringer, Blackfoot, 38 Special, Rabbit (old band), Joe Satriani, Reo Speedwagon, Angel, Starz, Foghat, ZZ Top, fuck too many to remember.... Oh yea Bad Company, Billy Idol, Bill Squire, Collective Soul, Cheap Trick, Deep Purple (Perfect Strangers Tour), Greg Kihn Band, Heart, Foreigner...... The Godz !!!! Crazy ass biker band from Columbus from the late 70's Nazareth, Michael Schinker, Night Ranger, The Offspring... I give up... Too many brain cells have died, my memory is shot.
