Great album. I used to listen to it in the dark with headphones in my room at night in high school.
You may not get a chance to see Pink Floyd live again (I was fortunate enough to see them once), but I would commend unto you
The Machine. They are a Pink Floyd tribute band. I have seen them a couple of times, most recently last weekend at The State Theater in Falls Church. They do an excellent job not only recreating the sound, but they put on a decent light show as well.
I see you are in Texas, and looking at their posted tour dates, I don't see a stop there anytime soon. You may want to keep an eye out though.
