By October 1968, the Grateful Dead were deep in one of the most exciting and unpredictable stretches of their early career. The band that had emerged from the Haight-Ashbury psychedelic scene was now a seasoned live unit, road-hardened and pushing further out into improvisational territory with each passing show. This was the classic early lineup — Garcia, Weir, Lesh, Pigpen, and Mickey Hart, who had joined the previous year to form the dual-drummer configuration that gave the band such an unusual rhythmic foundation. Their self-titled debut had been out for over a year, and Anthem of the Sun, that gorgeous, studio-collaged artifact of their live explorations, had dropped in July. The band was living somewhere between those two records in real time, finding the extended psychedelic sprawl that would define their legacy. The Avalon Ballroom was the other great San Francisco ballroom of this era, the Fillmore's sibling and rival, run by Chet Helms and the Family Dog collective. If the Fillmore was the more polished operation, the Avalon had an earthier, more communal feel — smaller, sweatier, and deeply tied to the Haight scene the Dead had come up in. Playing the Avalon in late '68 was the band playing a kind of home game, in front of an audience that had been with them since the beginning, in a room that had helped define the sound and culture of the entire psychedelic era.
The one song we have confirmed from this show is Cryptical Envelopment, and it's a fascinating window into this moment. That brooding, minor-key piece — Garcia's voice riding just above a dark, churning groove — was written as the twin bookend to The Other One, one of the Dead's most fearsome early improvisational vehicles. To hear Cryptical in a live setting from 1968 is to hear the band at the threshold of something enormous. The way it could pivot from quiet menace into full-throttle chaos, with Lesh's bass taking on almost melodic authority and the two drummers building a wall of rhythmic pressure, was something genuinely new in rock music. Recordings from this period vary considerably in fidelity, and anything surviving from the Avalon in '68 carries the charm and grit you'd expect from early audience or lo-fi sources — close your eyes and you're there. Whatever the sonic limitations, the sheer aliveness of the Dead in this room, in this year, is worth every bit of tape hiss. Press play and hear where it all began to open up.
