In 2015, seven complete concerts from the weeks leading up to the shows heard on Yessongs were assembled in the 14-CD boxed set "Progeny: Seven Shows From Seventy-Two." On December 2, the boxed set will make its vinyl debut in a monumental 21-LP version.
This 3-CD set is for true Flash fans. The packaging is gorgeous, there’s a beautiful 32-page booklet with lots of good information and rare photos, and the discs are a treasure trove of seldom-heard live recordings
