These discs explain why Elvis became such an influential and towering rock 'n roll artist. His talent shows through on all of these songs and it's simply a great introduction for fans who are only familiar with the King's later work. I prefer the early Presley, and all the hits are here, but more importantly, his other, lesser known songs, are here as well. How about Baby You're So Square, one of his most charming and fun recordings? Another gem is Don't You Think it's Time. Even Here Comes Santa Claus is a stellar performance!Another great feature is that you can hear Elvis develop his vocal style. There are three different versions of the fabulous Shake, Rattle and Roll, and on each successive version, you can hear the improvements, both vocally and instrumentally. This is a piece of music history and will show even a casual listener that Elvis was amazingly gifted as a vocal innovator and rock stylist. Highly recommended!
