A series of live recordings that have been lurking in the Yes archives for decades will make their long-overdue official debut in May.

Classic Rock magazine shares the details of the new release, which consists of performances recorded during seven live dates in late 1972. As the report notes, these shows marked the trial-by-fire debut of drummer Alan White, who was given a mere three days to learn the repertoire after Bill Bruford quit Yes to join King Crimson.

The seven shows in question, starting with their Oct. 31, 1972, performance in Ontario and concluding Nov. 20 in Uniondale, N.Y., found the band touring Canada and the Eastern U.S. while road testing the new lineup in advance of the concerts that ultimately made up the bulk of 1973's triple live Yessongs LP.

Available as a 14-disc box titled Progeny: Seven Shows From Seventy-Two as well as a truncated 10-song, two-disc set titled Highlights From Seventy-Two, the set comes in a slipcase box, with artwork (including a "refreshed" Yes logo) courtesy of Roger Dean, as well as painstakingly restored audio that the band promises "drops listeners right into the front row."

Both titles are scheduled for a May 4 release; for more information, including pre-order links and a liner notes essay penned by Syd Schwartz, visit the Yesworld site.
