I was at this concert and also have the video of it. A great show that was about four hours! Very enjoyable. This disc is a good summation of the evening with some of the more well-known tunes by each artist presented for your approval. Joe, Eric, and Steve all played well and energetically. I don't see this as particularly essential because most of these songs are already available and some have been played to death. For me this would be more of a novelty item, but perhaps the curious new listener will find it a nice jumping-off point.
