By the spring of 1985, the Grateful Dead had settled into a muscular, arena-ready version of themselves that remains somewhat underappreciated in the broader fan conversation. Brent Mydland, now six years into his tenure as keyboardist, had fully grown into the role — his Hammond B3 and synthesizer work lending the band a harder-edged, almost churchy power that distinguished this era from the floating, psychedelic textures of the Keith Godchaux years. Jerry Garcia's guitar playing carried the weight of a man who'd survived a serious health scare the previous year, and while the band's 1985 touring found them working hard through the winter and spring, there was a focused, road-worn intensity to many of these shows. Garcia, Weir, Lesh, Hart, Kreutzmann, and Mydland — the classic mid-eighties lineup — were a tight, professional unit, even if the highs weren't always as transcendent as 1977 or as exploratory as 1972. Portland, Maine isn't a city that looms large in Dead lore, but the Cumberland County Civic Center was a reliable mid-sized stop on the kind of regional Northeast swing the band worked regularly through these years. Capacity crowds in a hockey arena — enthusiastic, often young, and primed for a party — were typical of this circuit, and the Civic Center's acoustics, while not exactly legendary, gave the band enough room to stretch out without swallowing the sound whole. The two songs represented in the database here tell an interesting story about the show's character.
"Iko Iko," the joyful, rhythm-forward Mardi Gras staple the Dead adopted in the early seventies, was a crowd-pleaser and a palate cleanser — often dropped into sets to get bodies moving and spirits lifting, with Brent frequently taking it and running. The transition from "He's Gone" into what follows (that ">" notation hinting at a segue) is where things get genuinely interesting. "He's Gone" in this era could be a slow-burn elegy or a building, gospel-inflected cry, and when the band decided to push it somewhere instead of letting it resolve cleanly, the results could be remarkable — a segue into "Truckin'" or a jam of its own was always a possibility worth waiting for. Listeners should pay close attention to the bass and drum interplay in "He's Gone," and to whatever Brent is doing harmonically during its final passages. The recording circulates in a few audience versions of reasonable quality for the era — not a pristine soundboard, but enough to let the music breathe. Cue it up and let March of '85 do its thing.
