Once Keith Jarrett gets into a concept, he likes to keep those tapes rolling. This two-disc live outpouring from a Standards Trio gig at Munich's Philharmonic Hall was the biggest offering from this group up to that time (it wouldn't hold that distinction for long) -- and once again, Jarrett treats his brace of pop and jazz standards with unpredictable, often eloquently melodic and structural originality. To cite a pair of highlights: "Autumn Leaves" always seems to bring out an endless flow of invention from Jarrett, and "The Song Is You" gets off to a rollicking start and maintains a nearly relentless energy level for 17 minutes, closing with a Spanish vamp. Again, the rapport with his onetime jazz-rock associate, drummer Jack DeJohnette, and bassist Gary Peacock is total;DeJohnette's mastery of shifting cymbal patterns while maintaining the pulse acts on the trio like a loose tether made of carbon steel. There is a considerable amount of Jarrett vocalizing, though; sometimes he sounds like a tortured animal. CD buyers get "Billie's Bounce" as a bonus.
