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.
Kind of Blue isn't merely an artistic highlight for Miles Davis, it's an album that towers above its peers, a record generally considered as the definitive jazz album, a universally acknowledged standard of excellence. Why does Kind of Blue posses such a mystique? Perhaps because this music never flaunts its genius. It lures listeners in with the slow, luxurious bassline and gentle piano chords of "So What." From that moment on, the record never really changes pace – each tune has a similar relaxed feel, as the music flows easily. Yet Kind of Blue is more than easy listening. It's the pinnacle of modal jazz – tonality and solos build from the overall key, not chord changes, giving the music a subtly shifting quality. All of this doesn't quite explain why seasoned jazz fans return to this record even after they've memorized every nuance.
