This already got reviewed in last Sunday's SF Chronicle:
MILES DAVIS: THE CELLAR DOOR SESSIONS 1970
In the light-speed evolution of Miles Davis’ electric ’70s period, one album stands like a marker. “Live-Evil,” though released only two years after the groundbreaking space-jazz of “Bitches Brew,” is galaxies apart from that effort and contains inklings of the psycho-funk Davis would achieve a year later. But “Live-Evil” was a hodgepodge, with some tracks recorded live at the Cellar Door club in Washington, D.C., and others from an earlier studio date with different personnel. The great stuff was from the Cellar Door, and the new six-CD box set has it all: four nights, eight sets, with Davis on trumpet, Gary Bartz on sax, Henderson on bass, Keith Jarrett on electric piano, Airto Moreira on percussion, Jack DeJohnette on drums and — for one night — John McLaughlin on electric guitar. If “Bitches Brew” was the journey, “Cellar Door” is the arrival at the deep and the dark. -- David Rubien
