Along with its sister recording, Pangaea, Agharta was recorded live in February of 1975 at the Osaka Festival Hall in Japan. Amazingly enough, given that these are arguably Davis' two greatest electric live records, they were recorded the same day. Agharta was performed in the afternoon and Pangaea in the evening. Of the two, Agharta is superior. The band with Davis – saxophonist Sonny Fortune, guitarists Pete Cosey (lead) and Reggie Lucas (rhythm), bassist Michael Henderson, drummer Al Foster, and percussionist James Mtume – was a group who had their roots in the radically streetwise music recorded on 1972's On the Corner, and they are brought to fruition here.
None of Miles Davis' recordings has been more shrouded in mystery than Jack Johnson, yet none has better fulfilled Miles Davis' promise that he could form the "greatest rock band you ever heard." Containing only two tracks, the album was assembled out of no less than four recording sessions between February 18, 1970, and June 4, 1970, and was patched together by producer Teo Macero. Most of the outtake material ended up on Directions, Big Fun, and elsewhere. The first misconception is the lineup: the credits on the recording are incomplete. For the opener, "Right Off," the band is Miles, John McLaughlin, Billy Cobham, Herbie Hancock, Michael Henderson, and Steve Grossman (no piano player!), which reflects the liner notes.
