Here we get 40 excellent Johnny Cash songs from the Sun Records period. These are all in excellent sound quality as well. You can't go wrong with this material at all.
One questionable part of the release: The songs on the second disc are all in alphabetical order, except for two selections. This shows me that they put the main, best known, songs on disc one and threw the rest on disc two. It doesn't do anything for the enjoyment of the material, but where else have you seen that happen?
There are simply too many good songs on these discs to NOT pick it up. If you want to dig deeper into Cash's Sun period, this is the place to go. Outstanding!
