On Allmusic, Lindsay Planer said, "Incrementally, this [lineup of the Grateful Dead] began distancing the band's sound from the R&B-meets-psychedelia of the Ron "Pigpen" McKernan years, as well as the more recent rural twang heard on Workingman's Dead (1970) and American Beauty (1970). Instead, their collective fusion-based explorations continually challenge the musicians, while simultaneously providing fresh extensions and visages on familiar favorites. Nowhere is this more evident than on "Playing in the Band". After introducing the number in their repertoire (circa February of 1971), they cultivated it from a fairly rote and otherwise typical rendering into an unexpurgated show-stopping centerpiece — as shown by the pair of 20-plus minute excursions on Dick's Picks Volume 31. They not only clock in at nearly half an hour apiece, but each is distinctive and examines the Grateful Dead's ability to end up at different places, despite the similarities in the point(s) of departure."[2]
In The Music Box, John Metzger wrote, "Just days before Richard Nixon resigned his position as President of the United States to avoid impeachment, the Grateful Dead unleashed a trio of exhilarating performances in the mid-Atlantic. For certain, 1974 was a magnificent year for the band — even if it was the end of a rather disgraceful era for the country at large — for its mad-scientist amalgamation of country, rock, jazz, and blues blossomed beautifully, and although it soon would take a 20-month sabbatical from touring, its energy remained remarkably high. Indeed, the 31st edition of the esteemed Dick's Picks series culls material from the early August conclusion of the Grateful Dead's summer tour, and although it mixes and matches among the concerts to form what is essentially two shows, it does so in a seamless fashion, providing an intriguing and frequently mind-bending blast through the group's much treasured canon."[3]
Booklet and essay
The release includes a booklet made of five sheets of paper stapled together, yielding a 20-page enclosure. The front duplicates the cover of the CD and the back features a short list of "Upcoming gigs" that include the shows in Philadelphia on August 4 and 5.
Most of the booklet is a long essay from The Aquarian by Jay Saporita entitled "We used to play for silver, now we play for life", a verse from the band's song "Jack Straw". Spanning the better part of 16 pages, the essay details the several days spent setting up and performing the shows, and includes highlights from moments backstage.
The last page of the essay features a large color photograph of the Wall of sound, and the last two pages list the contents of and credits for the release.[4]
Caveat emptor
Each volume of Dick's Picks has its own "caveat emptor" label, advising the listener of the sound quality of the recording. The label for volume 31 reads:
"Dicks Picks Vol. 31 was mastered from the original 2 track analog source tapes, running at 7.5 IPS, recorded during the last American tour using the famed Wall Of Sound. Some sonic anomalies remain, particularly some over-exuberant piano-related sounds, but we have done as much as possible to bring the Wall Of Sound into your living room. Enjoy."
