Bitches Brew bridged the gap between rock and jazz, and once Miles Davis got his mitts on this demographic, he went right for the throat with a four-night stand at Bill Graham’s Fillmore East that June. Taped and edited for the classic live LP At Fillmore, this third volume of Davis’s own Bootleg Series compiles the entirety of this historic run with his electric septet, rounded out by saxophonist Steve Grossman, keyboardists Keith Jarrett and Chick Corea, bassist Dave Holland, drummer Jack DeJohnette and percussionist Airto Moreira. “You can hear the anger and darkness and the craziness of everything that was still in the air from the ‘60s when this music was made,” proclaims Carlos Santana in the liner notes to this four-disc collection, perfectly encapsulating the mood of a room enrapt by the psychedelic swirl of unbridled improvisation on runs through era-appropriate compositions such as “The Mask,” “The Theme” and “Willie Nelson.” If electric Miles is your thing, then this collection is as indispensable as the original Brew itself.
