The 35th installment in the King Crimson Collectors' Club finds the 1972 quartet of Robert Fripp (guitar/Mellotron), Mel Collins (saxes/flute/Mellotron), Boz Burrell (bass/vocals), and Ian Wallace (drums) in the Mile High City at the Sound Track on March 13, 1972. Parties who follow the series' chronology could easily consider Live in Denver, CO 1972 (2007) a companion to the ninth volume Live at Summit Studios, 1972 (2000) -- which was documented the previous day and subsequently broadcast on KFML in Denver, CO. And what a difference 24 hours has made. Despite purported internal difficulties among the players, they deposit all dissension at the stage door and put on what must surely rank as one of the loosest shows in the band's history. The combo hit the road touring in support of their recent long-player Islands (1971) -- which was the fourth to be issued under the King Crimson moniker. Understandably, half of the contents are dedicated to presenting all but two of the album's six sides. The coupling of the lovely and evocative "Formentera Lady" and the intense instrumental "Sailor's Tale" open the set, mirroring their placement on Islands. Collins' sharp and penetrating blows are an essential element to the success of the latter selection as both he and Fripp sonically taunt each other into some interesting areas. The demented big top Lizard-era (1970) track "Cirkus" comes alive under the guidance of these performers -- particularly Burrell's ethereal lead vocals, which are matched by the equally off-kilter Mellotron and VCS 3 electronic effects. Fripp takes the microphone for a rare introduction -- with a wink and a nod -- to an hilarious attempt by the boys to keep a straight face during "Ladies of the Road." Obviously an inside joke pertaining to the number's carnal nature hits all-too-close to home and Wallace is barely able to contain himself throughout. Likewise, Fripp can be heard riffing and adding parts with atypical whimsy. The camaraderie continues through the sublime "Letters" -- which Fripp tags with an off-the-cuff coda. All hellfire then breaks loose for the quarter-hour plus bluesy-fuelled "Groon" that again is unlike the usual readings that are fast and furious improvisations. Wallace goes native as the VCS 3 makes his percussion take on an out-of-control Caribbean steel drum vibe. What could possibly put a cap on such an inspired endeavor? Nothing short of a two-fisted conclusion underscoring the doubled-edged nature of King Crimson. Returning to where it all began, they unleash a beastly "21st Century Schizoid Man" before sending everyone home with the sublime In the Wake of Poseidon (1970) ballad "Cadence and Cascade." Unquestionably, Live in Denver, CO 1972 is one of the most unexpected treats to have come from the mighty Crim's vaults as even jaded enthusiasts will find many moments worth discovering over and over.
