I have seen pink Floyd five times and Roger Waters once. Roger was during his Radio KAOS tour. Pink Floyd is one of the few groups I have seen that can replicate their studio sound almost to perfection. There were times if not for the audience, you'd swear you were just listing to the album. Truly gifted at their craft.
The first time I saw them I was 16. I can remember I was sitting next to this large group of biker dudes that had me a little intimidated. At one point in the show, a few joints were being passed down the row and this dude next to me that looked like Billy Gibbons nudged me on the shoulder and handed me a joint. At that time I had never smoked so I just passed it on to my buddy and on down the line. I think Billy could tell I was a little out of my element. He smiled and said something to me along the lines of "Good for you man, I don't smoke the stuff either". From then on Billy and I exchanging pleasantries between songs and after the show was over I remember he shook my hand and something like "keep rocking dude".
The fourth show was the best concert I believe I have ever seen. It was at Texas Stadium before they tore it down. We were sitting about midway on the floor which positioned us right under the hole in the roof. Some time during the show it started to lightly rain and the lasers would seem to bounce off the rain drops. They had this one blue laser that went across in a flat line and then slowly went up and down like a wave. With all the rain glittering through the laser it looked like ocean waves crashing. We sat there under the ocean looking up in rain, watching the waves crash over the top of us. I bet I've seen close to 40-50 shows in my life and that night was the best night I can remember. Good times.
