By the fall of 1985, the Grateful Dead were deep into the arena rock phase of their long strange trip, and the band that took the stage at the Sun Dome in Tampa, Florida that October night was a road-hardened unit firing on all cylinders. Brent Mydland had by this point fully grown into his role, no longer the new guy who replaced Keith Godchaux back in 1979 but now a confident, soulful anchor whose Hammond organ and bluesy vocals had become inseparable from the band's identity. Garcia's tone in this period was sharp and singing, and the rhythm section of Bill Kreutzmann and Mickey Hart — reunited since 1974 — gave the band a muscular, propulsive quality that suited the larger rooms the Dead were now regularly filling. This was an era of consolidation and confidence, the band touring hard in support of what had been a remarkably consistent run through the mid-eighties. The Sun Dome itself, which had opened just a couple of years prior on the campus of the University of South Florida, was a relatively new addition to the Dead's touring map. A large multipurpose arena seating around ten thousand, it was part of that expanding circuit of mid-size venues the band was gravitating toward as their audience grew through the decade.
Tampa had always been welcoming Dead territory, and the Florida faithful were known for bringing genuine heat to these shows. What we have documented from this particular night is Space, that exploratory free-form interlude that the Dead inserted nightly between the second set's more structured peaks and its closing run. Space is where the band dissolved all genre conventions and went genuinely somewhere else — Garcia, Weir, and the Harts trading sonic textures and abstract shapes with no predetermined destination. In 1985, these passages could stretch and breathe in genuinely unsettling ways, and a strong Space from this era has a kind of paranoid beauty to it, the whole band listening as much as playing, following whatever thread emerged from the collective unconscious of the room. The recording circulating for this show should give you a reasonable window into the evening's atmosphere — worth dialing in with headphones to catch the subtle interplay happening in those exploratory passages. If you love the darker, more atmospheric side of the Dead's improvisational vocabulary, this is exactly the kind of night worth pulling up on a quiet evening and letting wash over you.
