This nine-disc box set gathers music from a trio of consecutive Grateful Dead gigs — November 9 — 11, 1973 at their hometown hockey rink Winterland Arena. At the time the band consisted of Jerry Garcia (lead guitar/vocals), Donna Jean Godchaux (vocals), Keith Godchaux (keyboards), Bill Kreutzmann (drums), Phil Lesh (electric bass/vocals), and Bob Weir (rhythm guitar/vocals). In 1973, they atypically played a mere handful of gigs in San Francisco. According to Dennis McNally's liner notes, the run represented within could be considered over half of their Bay Area appearances for the year. That shouldn't suggest that the combo weren't keeping a full calendar, as they played about every five days or so for a total of 72 live shows. As the overwhelming bounty of strong performances on 2008's Winterland 1973: The Complete Recordings substantiates, the combo were operating on all cylinders and — when applicable — at full velocity. Hearing the natural ebb and flow inherent in the concerts themselves reveals the Grateful Dead's singular ability to effortlessly vacillate between a multitude of styles. Among them are straight-ahead vintage rock & roll — namely Chuck Berry's "Johnny B. Goode" and "Around and Around" — to covering country & western troubadours Johnny Cash ("Big River,") Marty Robbins ("El Paso"), and George Jones ("The Race Is On"). An amalgam of these artists would heavily influence the writing of Weir and John Barlow as the originals and Grateful Dead songbook staples "Mexicali Blues" and, to a more refined degree, the tales-from-the-road sensibility of "Black-Throated Wind" and "Looks Like Rain." Another facet of the hydra-headed Grateful Dead reaches back into their formidable psychedelic past, while Garcia, Keith Godchaux, and Kreutzmann are simultaneously aggressive in their pursuit of a jazzier grade of instrumental improvisation. Nowhere is this as evident as during the multiple stretched-out epic and exploratory readings of "Playing in the Band," "Eyes of the World," and "Weather Report Suite." Likewise, each night brought a host of undeniably special musical moments....
