Query: Ripoff!

The DVD consists of unwatchable, out-of-focus home movie quality footage that doesn't match the corresponding audio. For example, the footage shows Pigpen singing during the verses of Casey Jones, which Garcia sang. The CD is a chopped up, out-of-seqence soundboard recording with several midsong cuts. Surely there must be better documents of the Dead in 1970. Save your money!
