Every music collection should have a copy of Elvis' Sun Sessions. There are many versions available, this one is the complete 2CD version including alternate versions and the complete Hayride Recordings. This is where Rock and Roll had its roots and inspired many a musician since. Just to hear the opening strains of "That's All Right Mama" or "Mystery Train" still sends shivers down my spine. I never get tired of listening to these classic tracks.
