Delicate Sound of Thunder - I listened to the re-release that has the whole concert and supposedly much better sound quality. They play all of MLOR, and that album sucks, but some of it benefits from being freed of '80s studio production (although I don't know how much of that is the contemporary remastering vs. what it sounded like if you were there). The rest would have been a good concert if you were there, but now it's just a souvenir.
Pulse - This is also unnecessary to listen to now, but the concert is better. The Division Bell crap is all boring crap, but they don't play the entire album. This would have been fantastic to see live, even with a handful of shitty news songs, but there's not alot of reason to revisit the recording.
Roger Waters In the Flesh - This is actually worth listening to repeatedly, because the songs actually sound different, but still close enough to the originals that you'll probably like them if you liked the studio versions. And the play Dogs! Pink Floyd never played anything from Animals after 1977. I was wondering if I should check out his solo career, which I strangely never got around to, but I hate the solo songs from the '80s that he plays here. There aren't that many of them though, and everything else is good.
