Query: Demonic jazz rock

Miles Davis early-mid 70s explorations(beginning with Bithes Brew) are now legendary. This album is the culmination of his experiments.Here he welds together the seemingly polarised sounds of Jazz, Sly Stone-like ensemble playing and James Brown/Fela Kuti funk grooves. All this enveloped by screeching Hendrixian guitars. The Maestro himself adds to the 'wall of sound' with his own wah wah processed trumpet and overdriven organ.The results are staggering. No one pushed the envelope as far as Miles did.Interested listeners should also sample the companion concerts to this - Pangaea and Dark Magus
