From the original press-release:
Compared with its previous release, the evening show is vastly superior in sound. It was not taken from the same compact cassette source you have heard on the FTD soundboard release 'Live In L. A.', but comes from an original reel-to-reel soundboard tape transfer! The sound difference is like night & day. The afternoon show has much improved sound too, coming from the original audience recorded mastertape. The sound (although not excellent) is clearer than before and most of the (disturbing) distortion is gone. In recent years, some younger fans claimed that Elvis' performances in LA were mediocre. Nevertheless, fans who were present always mentioned these were "kick-ass performances". It's worth mentioning that these shows were attended by a few members of the hard-rock band 'Led Zeppelin' as well as by Bill Wyman, bass player from The Rolling Stones.The 120-page book is filled with many brand new photos of great quality (both b/w and colour) and what’s most important, more than 120 images have never before been published anywhere!This special audiovisual set will mark the ultimate release of Elvis Presley's live appearances at the Los Angeles in May ’74. Every second was digitally restored to achieve the best possible result. This is the first-ever Audionics real audio-visual presentation. It’s a special set which deserves a place in any serious Elvis collection!
