By September 1991, the Grateful Dead were deep into the final chapter of their long strange trip, and the weight of that was starting to show in the music — sometimes transcendently, sometimes unevenly. Brent Mydland had died the previous summer, and Vince Welnick had come aboard as the new keyboardist, joined by Bruce Hornsby sitting in on piano through much of 1990 and into '91. Hornsby was still contributing regularly around this period, adding a classical and bluegrass-inflected touch that pushed the band into genuinely new harmonic territory. Garcia, meanwhile, was managing his health with varying degrees of success, and the band was playing through a heavy touring schedule that had them in the northeast in late September. The whole ensemble had a certain road-worn momentum to it — they were a machine that knew how to run, even when the fuel was getting low. Boston Garden was a storied barn of a place, the old parquet-floor arena that had hosted Celtics championships and Bruins playoff runs, a building that smelled like history and hockey ice. It wasn't the most acoustically forgiving room in the world, but Dead shows there tended to carry a raw New England energy — Boston crowds were loud, opinionated, and deeply invested, the kind of audience that had been following the band since the early days at the Roxbury venues and the Boston Music Hall.
Playing the Garden meant playing big, and the band generally rose to that context. The fragments we have from this show offer a tantalizing slice of the night. "Just Like Tom Thumb's Blues," the Bob Dylan cover, was a tune the Dead could inhabit with real soulfulness — a melancholy, cinematic song that gave Garcia space to dig in vocally, and when he was locked in, those performances could be quietly devastating. The tape flip after the song is a small frustration, but what's there is worth your time. "They Love Each Other," a Garcia-Hunter composition that had been a setlist staple since the early seventies, tends to bring a warm, rollicking energy — a crowd-pleaser that also gives the guitarists room to stretch. And "Cassidy," with that arresting, galloping rhythm that Weir anchors so well, is the kind of opener or set piece that can crystallize a whole show in a few minutes of pure drive. Recording quality and source information for this one may vary, so go in with flexible expectations — but whatever you're hearing, let the Cassidy rhythm lock you in and ride it from there.
