The sound quality is very good. It's among the best sounding Elvis live recordings, strictly from an audio point of view. Of course by the time, Elvis wasn't half the performer he used to be, so from a performance point of view, it's inferior to older recordings. But for the most part, the performances here are decent, although there is a 'been there, done that' feel to a lot of them.
Probably the most interesting recordings here are the undubbed versions of two of the songs that ended up on Elvis' last album (Moody Blue). The songs are Unchained Melody and Little Darlin'.
The one that sounds the most different is Unchained Melody, which apparently had quite a bit of overdubbing done on it. Here it is Elvis at the piano accompanied only by a guitarist.
While this isn't Elvis at his best, it should be of interest to Elvis' most devoted fans.
