These are four historic performances from the Fillmore East and West in 1970, at a time when Miles Davis was single-handedly bringing Jazz into the commercial Rock era. In their unedited form, all selections are previously unissued. The searing white heat of these concerts, originally issued in severely edited form, are now made whole. This set includes several bonus tracks like Wayne Shorter's "Paraphernalia" and "Footprints", an early version of "Miles Runs The Voodoo Down" plus a rare encore performance of Bitches Brew's "Spanish Key".

The visionary Bill Graham had booked Miles on a bill with The Grateful Dead at the Fillmore West and with fellow Columbia artist Laura Nyro in June 1970. The latter recordings are the earliest documented live performances of Miles's band when he hired two keyboardists--Chick Corea and Keith Jarrett, along with saxophonist Steve Grossman who had replaced Wayne Shorter. The rest of the rhythm section--keyboardist Corea, bassist Dave Holland, drummer Jack DeJohnette and percussionist Airto Moreira--were in the backbone of this band throughout this explosive period.

Curated by Carlos Santana, this set features fascinating firsthand accounts and profound insight into a seismic shift in American society, music, and culture. In a rare, in-depth interview, Miles--while listening to the concert playback--was "so excited about the music that he wanted every set, every note made available to the public..."
