If you can find the latest Mojo mag, pick it up. It has a most excellent article w/ Roger Waters about PF, plus the difficulties & triumphs of The Wall live, as offered by various musicians & technicians. I'm not much of a Floyd fan, but it was really cool to read how they managed to deal with the technical aspects of the show.

Plus there's a free CD w/ the mag w/ disc 1 of The Wall done by various bands. Not too shabby. Next month, disc 2.
