The complete Portland Memorial Coliseum concert from 5/19/74 is released across six 180-gram vinyl LPs. During the period when the shows were recorded, the Grateful Dead included: Jerry Garcia, Donna Jean Godchaux, Keith Godchaux, Bill Kreutzmann, Phil Lesh and Bob Weir. The 1974 shows were recorded just a few weeks before the band released its seventh studio album, From The Mars Hotel. The show was mastered in HDCD from the original master tapes by Jeffrey Norman at Mockingbird Mastering. The transfers from the masters were transferred and restored by Plangent Processes, further ensuring that this is the best, most authentic that this show has ever sounded.
