Getting back to Miles’ kinship with the post-psychedelic starsailors and aquanauts, the music of Dark Magus, On the Corner, Agharta, et al offers a drastic intensification of rock’s three most radical aspects: space, timbre, and groove (by which I something altogether more machine-like/matrix than jazz’s freeswinging drive). Making what he imagined was a sideways shift towards the pop mainstream (ha!), Miles actually achieved was a culmination of rock’s trajectory towards kinaesthetic abstraction, aka the textured groovescape.
