By the fall of 1985, the Grateful Dead had settled into a muscular, arena-ready version of themselves that doesn't always get its due. Brent Mydland was now several years into his tenure as keyboardist, having long shed the newcomer label and developed a voice — both literal and instrumental — that gave the band a harder, bluesier edge than the Keith Godchaux years. Garcia's guitar tone had evolved toward that compressed, clean-dirty sound he'd favor through the decade, and the rhythm section of Weir, Lesh, Kreutzmann, and Hart was as locked in as ever. The In the Dark album was still two years away, so this was the Dead in their comfortable mid-decade groove: not yet the MTV-era phenomenon they'd briefly become, but reliably powerful on the right night. The Centrum in Worcester, Massachusetts was a relatively new facility at this point, having opened in 1982, and it represented exactly the kind of mid-size New England arena the Dead had made their second home by this era — big enough for a real event, intimate enough that the sound could cohere. Worcester crowds tended to be enthusiastic, part of the dense northeastern circuit that kept the Dead's touring economy humming through the eighties. The songs documented from this show sketch an interesting picture of the night.
"Bird Song" is always worth tracking down in this period — it gave Garcia room to stretch into that floating, searching melodic space he inhabited so naturally, and Brent's organ could lift it into something genuinely transcendent when the band was on. "Brokedown Palace" as a closer carries the weight it always did, a tearful, hymn-like farewell that lands differently depending on how much road the band has in their bones by that point in a set. "Around & Around" was a Chuck Berry-rooted rocker that the band used to ignite second sets, and the segue indicated by the arrow suggests they were building momentum into something beyond it. "Kansas City" is a rarity worth seeking out — the classic R&B number gave Brent a moment to howl, nodding back to Pigpen's soul-drenched influence while sounding entirely of its own time. If a soundboard source exists for this date, the Worcester taping community was active enough that it likely circulated well; even an audience recording from the Centrum tends to capture the room's decent acoustics. Either way, cue up "Bird Song" first and let it remind you what this band could do when the night opened up.
