Unreleased Miles Davis Performances to Be Released Two hours of previously unreleased performances by Miles Davis, leading a band that included Chick Corea, Keith Jarrett, Dave Holland, Airto Moreira and Steve Grossman, will be included in "Miles at the Fillmore - Miles Davis 1970: The Bootleg Series, Vol. 3," a four-CD set to be released by Columbia/Legacy on March 25. The set includes what Legacy describes as the unedited recordings of the performances Davis and his group gave at the Fillmore East from June 17 to 20, 1970, with bonus material from Davis's April 11, 1970 performance at the Fillmore West. Like many of Davis's concert recordings, full versions of the Fillmore shows have traded hands among collectors for several years. The concerts took place shortly after the release of "Bitches Brew," an album in which Davis blended rock influences into his own increasingly personal and wide-ranging brand of jazz. His Fillmore dates were an attempt to reach the rock audience. He shared the bill with Laura Nyro at the Fillmore East and with the Grateful Dead at the Fillmore West. A heavily edited double-LP version of the Fillmore East performances, the tracks listed simply as "Wednesday Miles," "Thursday Miles," "Friday Miles" and "Saturday Miles" - that is, excerpts from one of the shows on each LP side - was released in October 1970 as "Miles Davis at Fillmore." On the new version, as on the 1997 reissue, the individual songs (among them, "Bitches Brew," "It's About That Time," "Sanctuary" and "I Fall in Love Too Easily") are separately tracked and identified. Pieces not included in earlier incarnations include "Paraphernalia," "Footprints" and "Miles Runs the Voodoo Down."
