Some, presumably earliest, copies of this 2LP included an envelope containing a reproduction ticket to the both the 6pm and 8pm performances, which the musical content is sourced from. Very good sound quality for an unofficial LP from the late 70s. The performances are historical. These are the sit-down, boxing ring performances that brought Elvis Presley back from teen-aged dollar drive-in movie obscurity back to the serious artist Elvis was capable of being. We're so fortunate to have Elvis' career re-birth captured in such good audio & visual glory. Available officially, in a variety of formats, but this bootleg title is an attractive piece and from a period in music industry history when RCA just wasn't aware of (or willing to satisfy) a market that still exists a couple generations later. A nice, quiet pressing too.
