The two Great Deceiver packages add up to arguably the definitive portrait of the great 1973-4 Crimson line-up (many fans' favorite). Though several songs appear three or even four times across the four CDs, the performances mostly differ significantly due to the group's heavy investment in improvisation. More importantly, the group's onstage speciality - free, open-ended improvisation (not only unrelated to any particular song but frequently arhythmic and atonal) - is heavily documented, and better represented here than anywhere else in the official catalogue.
Although volumes 1 and 2 (which, in the old format, would have been volumes 1+2 and volumes 3+4) are both outstanding - this one has the edge. In fact, out of all the KC live albums, this is the one to get first, or first-and-last if one must choose between them. ("USA" for all its fame, is nowhere near as good).
The material here is drawn from four shows across an eight-month timespan - Pittsburgh, Penn State (briefly), Toronto and Zurich. Almost all of the core repertoire is heard - "Exiles", "The Night Watch", "The Talking Drum" [now very much David Cross's tour de force], "Fracture", "Starless" [where Cross plays the fast solo, on violin instead of keyboards], and "Larks Tongues In Aspic" [the complete Part One and a strangely abbreviated Part Two]. There is also a seldom-heard classic ("The Great Deceiver" itself) and, more importantly, the long-neglected "Doctor Diamond", performed in various forms throughout 1973-74 but not recorded in the studio (the compilers have chosen the final arrangement, with a slow-paced, thoroughly-composed instrumental middle).
But this is just the garni du jour - the meat of the matter is the improvisation.
True, some of the tracks tagged Improvisation are just preambles to existing songs - but even they are capable of varying wildly ("Some Pussyfooting" and "Bartley Butsford" are nothing like the original prefaces to "Larks...1" and "Exiles", as well as being substantially different from the performances on albums like "Collectable King Crimson Vol. 1").
The more substantial Improvisations include delicate folk-jazz hybrids ("Daniel Dust") and straightforward hard-rocking ("The Golden Walnut", whose first half includes a germ of an idea that lovers of the "Red" album will recognise). But then there's the stuff in between - brace yourself! "The Law of Maximum Distress", "Clueless And Slightly Slack", "Wilton Carpet", "Is There Life Out There", "Some More Pussyfooting"...whether you describe this as avant-garde rock, electric free-jazz or something else, there's no mistaking some of the most hair-raising, edge-of-your-seat, far-out collective improvisation it is possible to listen to.
