I have the 1st, 2nd and 5th albums on both vinyl and cd. The vinyl sounds much better than the cd on the 1st and 2nd albums. Johnny is holographic in the extreme. The sound on the 5th album is also quite good, but the quality of the vinyl leaves something to be desired.
Best song in the set = Unchained. Also worthy of note is "Aloha Oe", the last song on the last album. What an inspired selection.
But hell ...every song in the series is good.
