Yeah, I'm sortof down on Proper boxes. I think they could sound better, but don't for obvious reasons, like they don't have original source metal masters, etc. nor a big remastering budget. The booklets are okay. . . they don't speak to ME because they're not geared to ME. So to new listeners to players I guess they work out fine. I also hate how they rarely include complete sessions and again, a new listener won't be too worried about that. So it's a good recommendation Ber.
I believe I have the concert on a GNP Crescendo disc, but yeah, the Classics don't have this. But what they do have is so good!
