This Cd comprises some of Elvis' greatest tracks from the SUN studio in Memphis along with some others from 1957. It is Elvis, nearly at his very best, which maks this CD one of the finest one could hope from any artist or group involved in the Rock genre. The SUN tracks are of course legendary. This was the moment when the youth culture was born and without it, there would have been no Beatles or Rolling Stones. The 60s started here and this moment is ecapsulated in this CD. Miss it at your peril. The RCA recordings from '57 have lost that edge, hence 4 stars and not 5, but nothing remains revolutionary that long! Elvis is still excellant as he sings Baby I Don't Care or the moody Young and Beautiful and these later tracks show why Rock n' Roll could not hold him. He was just far too good a singer; far too accomplished. 4 out of 5 and an excellant buy. I'd recommend it to anyone.
