Elvis Presley Sessionography

A few weeks ago I wrote about Peter Guralnick's books on Elvis Presley. During this I said that the huge Elvis biography lacks detailed information about Elvis's recording sessions. But, I said, there are other books which fill this gap.
Several readers then wanted to know which books I had in mind and what would be the best book on Elvis's recording sessions. The one I recommend is Elvis Presley - A Life in Music, written by Ernst Jorgensen. Ernst started as a record collector and Presley fan trying to find out who played which instrument on which session and when. In later years he became Marketing Director for BMG which owns RCA Records. And finally he became the RCA man for re-releasing Elvis's recordings thus having access to all the session tapes and documents.
So if not Ernst, who else would be able and willing to fully document Presley's recording history? Elvis Presley - A Life in Music is the ultimate book describing each and every recording session between 1953 and 1977. All the musicians are listed, all recorded songs whether released or not, original sources for the released versions, studio talk and much more. There is not much to add to this book and if you really want to find something to criticize, it would be that Ernst concentrates on the official RCA releases, leaving out bootlegs and such. But that's what you expect from an RCA executive.
If you are listening to Elvis music, you need to have this book!
