Keith Jarrett's process is an essential part of his art, and with Inside Out, he takes the logical next step from Whisper Not the acclaimed 2000 release that marked his return to trio playing after a 30-month hiatus necessitated by illness. Devoted to bebop repertoire, Whisper Not revealed Jarrett swinging, cherishing every note, conjuring melodies with a minimum of fuss and economy of means, carving long theme-and-variation lines, and deploying jagged syncopations in the piano's lower reaches. Inside Out finds Jarrett and trio companions bassist Gary Peacock, and drummer Jack DeJohnette exploring fresh terrain, by building collective improvisations from a blank slate, much as Jarrett did on several hundred free-associative solo concerts between 1971 and 1996. At the CD's core are three extended improvs and a stunning fragment entitled "Riot." In each instance, blues language is the common denominator. Each member has been involved in free playing since the early '60s, and they draw upon the full range of their experience to construct marvelously cohesive statements that feel structured despite the lack of predetermined material. Unencumbered by any predisposition except to listen and find material in the moment, the trio's improvisations avoid cliché while imparting the idiomatic nuances of phrasing and forward motion. A lovely reading of the standard “When I Fall in Love” rounds out the program. This is a groundbreaking event for the maestro.
