Edition on 180-gram audiophile vinyl, coming in a gatefold sleeve. 'Agharta' was recorded live in 1975, in Osaka, Japan. On this occasion Miles Davis performed with flautist and saxophonist Sonny Fortune, bassist Michael Henderson, drummer Al Foster, percussionist James Mtume, guitarist Reggie Lucas, and Pete Cosey, who played guitar, synthesizer, and percussion. Produced and recorded by Teo Macero, the albums four seemingly unstructured segments emphasize the playing of Davis sidemen rather than his own trumpet. It eschews both melody and harmony in favour of a combination of riffs, crossing polyrhythms, and funk-oriented grooves for soloists to improvise throughout.
