Hey Bill,
I definitely didn't intend to hurt any feelings when I was critical of the DP clip posted. Again, that performance was amazing for it's time. The sound quality and mix is good, especially considering the gear/tech they would have had available in '72. It was also recorded before I was alive to put things into perspective. I have tremendous respect for the musicians that paved the way for us today. Each subsequent generation of players, technicians, and innovators push the performance envelop and experience first.
I remember attending my first live concerts in the late 80's and how overwhelming the experience was. I saw most of the late 80's/early 90's touring arena bands. There were some great shows. I always left with ringing ears, a bit of a beer buzz and a grin from ear to ear. In my mind that was as good as it's gonna get, right? It didn't sound like the CD, but it still sounded good and it was about the experience.
Fast forward to the late 90's and the wife and I are in our local arena for Matchbox 20's Mad Season tour. I remember looking at the PA hang and chatting with the road crew about this new fangled line array thing. I had heard good things about the technology, but never experienced it. Well I was completely floored that night. At the time it was the best sounding live show I had been to by a wide margin. You could here every nuance. The reverb on the drums, finger noise on the guitar strings, the horn section sat in the mix perfectly. It sounded like the CD it had all the energy and sensory overload of a live show. No real AITR sound just great tones that sat perfectly in the mix.
Over the years that followed I experienced many great sounding shows in that arena and worked crew for many of them as well. It's like the live sound experience achieved what I heard in my head. It's not that the shows I saw when I was younger sounded bad, but the new shows sounded the way I heard them in my head.
That '72 DP show, to you, sounds the way a rock concert should. That is fabulous. It is what you perceive as great. Most likely because it's what you grew up listening to and it sounds right to your ears. I respect that and I'm not trying to convince you otherwise. At the same time what I hear as right is something different and I don't expect everyone to share that taste.
In short all is good!
