On AllMusic, Timothy Monger wrote, "Captured in the period between the release of the Grateful Dead's From the Mars Hotel LP and their touring hiatus that began in late 1974, this lively set from Jerry Garcia and longtime collaborator Merl Saunders has a comfortable, spontaneous ease to it.... By this point, the Saunders-Garcia partnership was already well established and their preferred venue, Keystone Berkeley, provided a relaxed space to try out the various facets of their funk, rock, and R&B repertoire....

The highlights, though, are in the extended jams, particularly the 19-minute "The Harder They Come", which feels like a dynamic zenith of this set.

"[5] On Grateful Web, Dylan Muhlberg said, "GarciaLive Volume Nine: August 11, 1974, Keystone Berkeley is like nothing you've heard previously from the Jerry Garcia catalog.

You'll be taken from your living room back to the intimate confines of the Keystone, Berkeley, for a night of infinite possibilities.

"[6] On Glide Magazine, Doug Collette wrote, "The nine selections of Volume Nine in this archival series well illustrate how a setlist can oftentimes barely scratch the surface of what went on below and beyond the songs documented in a given night’s performance.... Precursor to the band eventually dubbed Legion of Mary that coalesced later this same year, this quintet displays the same predilection to dig deeply into a groove, the depth of which recordist Betty Cantor-Jackson captures with her usual impeccable clarity (and which Fred Kevorkian preserves with his equally reliable mastering).
