By the close of 1980, the Grateful Dead had settled into a configuration that would carry them through much of the decade: Jerry Garcia, Bob Weir, Phil Lesh, Bill Kreutzmann, and Mickey Hart, with Brent Mydland now fully embedded at the keyboards after joining in 1979. Brent brought a harder-edged, more soulful attack than Keith Godchaux had, and the band was still calibrating around his presence — finding the new chemistry, discovering which corners of the repertoire he could own and which he'd reshape. This was also a period when the Dead were leaning into a more muscular, arena-ready sound without entirely surrendering the exploratory looseness that defined them. December 1980 finds them deep into the fall touring cycle, road-hardened and playing with the confidence of a band that had survived upheaval and come out swinging. Long Beach Arena was a comfortable stop on the Southern California circuit for the Dead — a mid-sized arena that drew the dense, devoted SoCal fanbase that had been showing up since the Fillmore West days. The Los Angeles region always had a particular electricity for Dead shows, a crowd that came in knowing the songs cold and pushed the band accordingly. Long Beach wasn't as mythologized as the Greek Theatre up in Berkeley, but it had genuine energy and the Dead returned to it reliably through the years as a road-friendly room with decent sound.
The one song we have documented from this show is Little Red Rooster, and it comes with a notable asterisk: Matthew Kelly sitting in on harmonica. Kelly, the harmonica player and vocalist best known from Kingfish — the band Garcia had moonlighted with in the mid-'70s — was a natural fit for this kind of deep-blues material. Little Red Rooster, drawn from the Willie Dixon and Howlin' Wolf tradition, was one of those rare songs that let the Dead root themselves firmly in the blues instead of taking flight from it. When played well, it's a slow, greasy groove with plenty of room for interplay, and Kelly's harmonica presence would have added a raw, earthy texture that the song absolutely calls for. Listen for the conversation between Garcia's guitar and Kelly's harp — the push and pull of two musicians who knew each other's musical language well. The recording quality for this show may vary depending on the source available, but any tape capturing Kelly's guest appearance with the band on this track is worth tracking down. That kind of spontaneous, blues-deep moment is exactly what kept people coming back, and it's exactly what you want to hear on a December night in Long Beach.
