The Cellar Door Sessions 1970 (2005)

The Cellar Door Sessions 1970 is the eighth boxed set in Columbia's stellar Miles Davis Series and the well still hasn't run dry. Recorded over four nights in December of 1970, the six-disc release presents a fierce, funk-centric version of the jazz trumpeter's heady fusion sound—most of which has never before been released (45 minutes appeared as 1971's Live-Evil). The lengthy circular grooves, freaky wah-wah horn riffs, and ear-singeing guitar runs (courtesy of John McLaughlin) make this a kind of Rosetta stone for the entire jam band universe, without the patchouli stench.
