So cool you got to go to the concert! I saw a cover band called the Machine once, and they were pretty awesome, though I'd like to see David Gilmour live if he still tours. I skimmed the Wikipedia link a bit, definitely a lot of info. Oddly enough that album was released on two labels, both EMI and Columbia. The U.S. release was on Columbia, definitely would buy that. Some of my fav vinyl is on Columbia. I'll have to check Wikipedia in the future, never thought of doing that.
