I have heard quite a few rock performers from the 1950s: Elvis Presley, Chuck Berry, Little Richard, Buddy Holly, Big Joe Turner, Carl Perkins, etc. And I must say that this CD is my very favorite CD of 50s music. Hey, I like Elvis Presley, but I realize that Big Mama Thornton was better than him. Her version of "Hound Dog" is so superior to his that it makes me wonder why his was the version that became so popular. And it's not just that one song, either. Instead, all of the songs on this collection are excellent. I suppose that some people would place this CD in the blues categoty, but I say that it is rock. Yes, this CD is rock and roll as it was meant to be. I hope that in 100 years from now when people make lists of the best rock music of the 20th century, the music from this CD will be high on their lists. If you have any interest at all in listening to music from the very birth of rock and roll, then this disc should make a very valuable addition to your collection.
