I gotta agree with the other reviewers here--all of the tracks are previously released material, over-polished by RCA and containing none of the live-concert feel of the FTD CDs. Tacking on the studio recording of "Viva Las Vegas" at the start and giving it that title is just a cheap marketing ploy. But, hey, if it reminds people of the greatness of Elvis Presley and dispels some of the unfair myths of him as just an overweight has-been in later years--fine with me.
In other words, if you know Elvis, skip this. If you're a casual fan or a newcomer, you'll be amazed at the power of his live performances. RCA never got it right, and they prove it again with this release. Like others, I just can't believe this is the best they could come up with on the big anniversary.
