Burbank 68 compliments Tiger Man and Memories as the definitive trilogy of the 68 special.
A box set would have been great, but I urge you to buy all three. This is sensational music, including pre-show reharsals and plus the second of the stand-up shows.
The sound quality is excellent, on this, a strong contender for the best music the King ever made.
Infact the 68 special as a forerunner to the MTV Unplugged concept, with Elvis and band-mates in the middle of a small audience, raw and gutsy, as good as he ever was and better than anyone else could have dared to be.
With the 35th anniversary of the 68 special next year I hear that a special DVD is on the cards: hopefully, with all of the footage from both stand-up shows, both sit-down shows, the original broadcast and rare footage!
