By the spring of 1983, the Grateful Dead were deep into what fans sometimes call the "Brent era" — a muscular, keyboard-driven sound anchored by Brent Mydland's Hammond organ and gospel-inflected vocals, which he'd been shaping since joining in 1979. Jerry Garcia, Bob Weir, Phil Lesh, and the drumming tandem of Mickey Hart and Bill Kreutzmann had by now settled into a confident road unit, and while the band wouldn't release a studio album until *In the Dark* in 1987, they were playing regularly and tightly through the early eighties, honing their craft in arenas and amphitheaters across the country. 1983 finds them in a transitional but often underappreciated stretch — not the transcendent peak of 1977, not yet the late-decade commercial resurgence, but a band that could still open up extraordinary spaces on the right night. Irvine Meadows Amphitheatre, tucked into the Saddleback Valley in Orange County, was a natural home for the Dead during this period. The outdoor venue had a devoted Southern California following, and the warm Pacific evenings suited the band's more expansive tendencies. The crowd at Irvine shows tended to be enthusiastic and knowledgeable, the kind of audience that fed the band's improvisational appetite without demanding the hits-only set that could sometimes flatten a performance elsewhere. What we have from this particular evening is a piece of the second set: Space, the band's free-form collective improvisation that typically emerged from the percussion duet — Drums — that Hart and Kreutzmann performed in the heart of every second set. Space is where the Dead fully left the map. No chord changes, no song structure, no safety net.
Garcia might coax long sustaining tones from his guitar while Lesh rumbled beneath and Brent added unsettling organ textures. At its best, Space sounded like the inside of a dream, or the outside of one. What listeners should tune in for here is the interplay between the guitarists and the keyboards — how themes emerge and dissolve, how the band navigates silence as much as sound. Even a brief Space excerpt can tell you a lot about where the band's collective head was on a given night. The recording quality of this fragment isn't definitively cataloged, but even a partial second-set capture from this era rewards the patient listener. If Space is what survived, it may well be one of the more arresting minutes of the evening. Press play and find out where they went.
