My first concert, I think, was Black Oak Arkansas. I was visiting a friend near Little Rock and she got us tickets for my birthday.
While stationed in Louisiana, I saw Arlo Guthrie in a dive of a bar. The place was so bad they had chicken wire across the front of the stage so the audience couldn't throw things at the performers. A group of my Army buddies and I heard that Peter Frampton was going to be in concert. So we drove down the night before and removed most of our brain cells with recreational pharmaceuticals. When we got to the ticket booth we were told Peter Frampton was not in concert. It was Frank Zappa! That was a bizarre experience. I also saw Alice Cooper at LSU sometime later. That was another bizarre experience.
Then while stationed in Germany, I went to quite a few concerts. Uriah Heep put on a fantastic light show, Queen was great for theatrics, and Santana got a standing ovation playing "Europa". Nazareth, I cannot remember anything about except that I was there. I was told that I was carried home. Good times... I hope.
I was/am a HUGE fan of Blue Oyster Cult. I have seen them in concert a few times. In Germany, we went to see them and Aldo Nova was the "warm-up" band. Talk about high energy. Wowza. I had a t-shirt signed by Eric Bloom. I wore that thing to a frazzle.
In 1984, in Karlsruhe, Germany they had The Monsters of Rock tour in a soccer stadium. It was so hot! There is no shade in a soccer stadium. AC/DC was headliner and that made David Lee Roth mad. He thought Van Halen should have top billing. He made an ass out of himself cursing at the audience, so everyone sat with their backs to the stage while he was up. Then Ozzie Osbourne came out and started spraying the audience with a garden hose to cool people off. He said he will never forget that we are the only reason he is on stage.
I don't recall the prices but on the tickets from Germany, they list the prices in DM (Deutsch Marks). This was decades before the "Euro". The wall was still standing in Berlin back then. The exchange rate was about 2 DM per dollar, so tickets ran about $8 -$9 advance and higher at the door.
