Ivan I am 50 and went to quite a few concerts in my teens and twenties. I was already into sound so I would like to think that I had a somewhat critical ear:
Here are a few I recall:
1 - The Who (or part of the Who) in the Sportatreum in South Florida. I am not even sure it was music. Just a mass of noise above the crowd. The venue was awful. It was like being inside a bong with dirty water and then the sound.
2 - Jimmy Buffet -1981 - I still talk about this one vocals were unintelligible. He also has some early moving leeco's that made a god awful racket. No contrast or black level in the early video projectors
3 - Journey in an outdoor stadium in Orlando 1982 - (Also Aerosmith, Hagar one of those rock super bowl deals) anyway. We were not on the field but the sound was excellent. Even the girls commented on how good it was - decent level outdoor concert possible
4 - Best intimate show I have ever scene was Al Stewart around the same time frame. It was in a small venue Tirrea Verde in St. Pete. The mix was perfect. His musicianship on the piano spectacular.
What I do remember is in 1980 the theater at my college had just pair of Altec Lansing VoT in an elevated room off either side of the proscenium arch. It was a 1000 seat facility. I remember walking the seats and we had decent even coverage, no large areas of combing. I was able to later add small fills for the first few rows. I was a student but the facility leaned on me heavily. It was my first pro "working" experience.
I know these are pretty lame descriptions. The memories are more vivid. Now that I wrote this I too would like to compare it to the sonic experiences we create today.
Some of the concerts I remember
My very first concert was "the Four Tops"-i got a free pass from a friend. The only thing I remember was during their set a speaker on house right started buzzing and making a lot of racket. It took awhile for them to figure out which one it was and "I guess" unplug it.
Blue Oyster Cult (Agents of fortune tour). I don't remember anything about the sound-but the laser show was AWSOME!!!!!!!!!!!!!! I had never seen a laser show (as most people had not back then) and it blew me away.
ZZ top (late 70s). The sound was so bad I actually left Just a big mush
Rush (1977) The only thing I remember is that they setup the PA and sidefills wrong. On house left the Main horns were double driver JBLs and the sidefills were single driver horns. On house right they used the single driver horns for Mains and double driver horns for sidefills.
J Geils Band -Blow your face out tour Probably the most fun I have ever had at a concert. Old Community system and I remember it sounding GREAT.
Charlie Daniels Band (Souths gonna do it again tour) The whole PA "appeared" to be 2x12" cabinets with no horns. The cabinets were stacked horizontal and vertical and TONS of C Clamps were used to keep the cabinets together-all different colors/sizes etc. I remember it sounding good
Ted Nugent/Foreinger/Black Oak Outside and they used the Call Jam PA. It was LOUD LOUD. Everybody sounded fine except Foreinger. The distortion in the system was "passable for Nugent and Black Oak but really made Foreinger sound bad.
Jimmy Buffett (1977) The local college gym where I saw a lot of bands in and I was very disappointed when I walked in. The PA was small. A pair of Altec VOT and some other cabinets. After the warm up band played they removed the other cabinets and just left 1 or 2 pair of VOTs. It was was of the best sounding PAs in that room-but not as loud as the other acts.
There were many others-but these just stick out a bit.
