14 DVD set with like 38 hours of footage called "all the years combine"

however, there is one bonus disc with
Five previously unreleased live performances from the Grateful Dead archive
Backstage Pass, the 1992 documentary directed by Justin Kreutzmann
Brand-new interview with Grateful Dead archivist David Lemieux
