Fleetwood Mac's self-titled album "Fleetwood Mac" is nice, good music that's well mastered. Their "Rumours" album is also very good.
I've recently been on a kick, trying to find good stuff on BluRay. I haven't really been looking for live performances, not even doing it for the video, although I know that's obviously what BlueRay is all about. The reason I have been looking for Blueray titles is the sound is so much better. I just noticed that movie soundtracks sounded night-and-day better than even the best CD recordings I have. I think a lot of it is the mix, in addition to the lossless format typically used. One that I found recently was "Chris Botti - Live in Boston". It's really excellent.
