This is a two record set and contains the music on the first CD of a two CD set. All the songs have been previously released on their live albums. Only one “Estimated Prophet” was unreleased it being from the Barton Hall show at Cornell University in 1977. I listened to side 1 which has “Saint Stephen from Live/Dead and “Bertha” and “Wharf Rat” from the Skull and Roses album. Side two has “Jack Straw” and “Truckin'” from Europe ’72. This record came out in 2018.
