1.) The CD, so far, is awesome. Got it from CDNOW, immediately ripped it, sync'ed it over and listened to part of it en route to work this morning. It's a recording of The Wall, live in concert, somewhere on the 80-81 tour (they say, but I can't remember where). It's actually released by Pink Floyd (but NOT "Pink Floyd(1987)", which means that Roger Waters is the main guy involved in its creation/distribution). (Insert lengthy legal history of Pink Floyd vs. Pink Floyd(1987) here.)

2.) I was thinking JUST that the other day actually. I suspect that's "a comin" in a future ID3 spec, but to my knowledge doesn't exist today.
