January 1968 finds the Grateful Dead in one of their most electrically raw phases — a band still in the process of becoming. Garcia, Weir, Pigpen, Phil Lesh, and Bill Kreutzmann (with Mickey Hart not yet in the fold, as he wouldn't join until the fall of that year) were deep in the psychedelic trenches, playing long, unpredictable sets that blurred the line between rock and pure sonic experimentation. Their self-titled debut album had dropped the previous year and their landmark *Anthem of the Sun* was still months away from release, meaning the band was actively workshopping the material that would define that record in front of live audiences. This was the Dead as a genuine underground phenomenon — before Woodstock, before the Wall of Sound, before the arenas — and the music carries a corresponding urgency and strangeness. Eureka, California sits in Humboldt County on the rugged northern coast, about 270 miles north of San Francisco. It's logging country, isolated and distinctly its own thing, and the Municipal Auditorium is the kind of mid-sized civic hall the Dead played when they were still touring the less glamorous rooms of the Pacific Coast circuit. There's nothing mythologized about this venue — it's not Winterland or the Fillmore — but that's part of what makes a show like this interesting.
These smaller rooms, filled with local freaks who may have caught word of the band through the underground grapevine, often yielded some of the loosest and most exploratory performances. The one song we have documented from this show is *New Potato Caboose*, which is itself a signal worth paying attention to. A Bob Petersen/Phil Lesh composition that appeared on *Anthem of the Sun*, the song was a staple of this era's deep space explorations — slow, hymn-like, and dripping with the kind of modal drift that Garcia and Lesh were perfecting in 1967 and '68. In live performance it could stretch into something genuinely other, a portal rather than a song, and catching it in January 1968 means hearing it in nearly its purest, most freshly-minted form. The recording situation for early 1968 shows is typically fragmentary — expect rough audience tape if anything survives, and treasure it accordingly. Even a murky document of the Dead in this period is a window into something precious: a band in the wild, not yet packaged for posterity. If this one circulates, press play and let it wash over you.
