In 1988, Columbia Records released a four-disc Roy Orbison retrospective called The Legendary Roy Orbison . It contained 74 tracks. It was a great package except for one thing: it sounded terrible, as the mastering techniques in the first days of the CD were not what they are now. The Soul of Rock and Roll, issued by Sony Legacy in 2008, is an enormous improvement in the sonic arena, just for starters. This four-disc collection contains 107 tracks (33 more than the previous box) with selections from all the labels Orbison recorded for. There are 12 previously unreleased performances, including the last tune Orbison ever committed to tape (strangely, a live version of "It's Over," recorded a scant two days before his death in Akron, OH).
