This previously unissued Monterey Jazz Festival set captures Miles Davis in transition. Davis' relatively new quintet (Herbie Hancock, George Coleman, Ron Carter and Tony Williams) plays material that defined his work with his previous group (which featured John Coltrane). Miles and Co. torque up "So What" considerably and deconstruct the standard "Stella by Starlight." Coleman would soon be replaced by saxophonist Wayne Shorter, and the next critical phase of Davis' musical journey would truly begin.
