The “Miles at the Fillmore – Miles Davis 1970: The Bootleg Series, Vol. 3” 4-CD box set has just been released last week, on March 25, 2014.
Here is is an excerpt from Thom Jurek’s review on AllMusic:
“Until now, the official recordings of Miles Davis’ performances at the Fillmore East between June 17 and 20, 1970 have been limited to Miles at the Fillmore, released as a double-disc. That album’s producer Teo Macero edited the recordings to create medleys of each night’s music to four 20-minute selections. This four-disc set contains the full concerts. There are 100 minutes of previously unreleased music from Wednesday through Saturday, and an additional 35 minutes of unreleased music from a previous gig at the Fillmore West.”
