I have been an Elvis fan since the 1960's. So I have seen his music released in various ways. As a marketing graduate I think bmg/sony have run out of steam for innovative strategies to release his music. If I may I would like to suggest the following:
In the early to mid 60's Elvis recorded a number of ballads that had some of his best vocal performances. However they were overlooked by spreading them as extras on sometimes bad movie soundtracks (not where they belonged. Examples of these were: Something Blue, That’s someone you'll never forget, Indescribably Blue, Starting today, Anything thats part of you, I met her today, Suspicion, You don’t know me, love letters, am I ready, please don’t stop loving me, and you'll be gone. These could have a new instrumental track (such as the new Beatle album ("LOVE) that was just released- the Beatle fans went crazy over that. Or remixed from the original . Marketing thois prject would have been about a selection of songs that actually create a concept piece of overlooked work.
A duet cd: there are many tracks spread over his career, "The lady loves me" with Ann Margaret would be great (watch the video- they were on fire doing this song) Edge of reality would sound great with Cher mixed in as a duet. Don’t cry daddy could be done with Lisa Marie (its on bootleg and sounds great)
A concept album where huge artists were allowed to remix and produce one song each ex: Paul Mc cartney, Bono, Celina dion- there are many huge entertainers that would love to do this as a collaborative project. It would breath an interesting a new array of interpretations of his music
