It contains the complete concert recorded at the PNE Garden Auditorium in Vancouver, British Columbia, on July 29, 1966.

[2][3][4][5][6] The same recording was previously released on CD on January 20, 2017, as the bonus disc for the 50th Anniversary Deluxe Edition of the Grateful Dead's eponymous first album.

[1] In an interview, Grateful dead archivist David Lemieux said that he had wanted to release this concert as an album, but it was too short for the Dave's Picks series.

"[9] Jeff Tamarkin, writing in Relix, said, "As for the jams, the Grateful Dead were still so raw and unformed in the summer of '66 – part garage/punk, part tough blues band, a bit of folk-rock and experimental zeal all filtered through a Prankster-informed lysergic mischievousness – but the elements are all in place.

They're still primarily a cover band at this stage – their own tunes are not even close to what they'd soon start turning out when Robert Hunter became involved – but there's no denying the inherent originality and enormity of what they've got going on.
