Nice!
I remember reading notes somewhere about miles interest in Jimi, and Jimi's desire to go towards a jazzy direction.
I feel that the impression Jimi had on Miles was quite big, as evident in Miles' jazz "rockier" excursions. I would believe that Jimi's improvisation power is right up there with Coltrane's, both possessing the ability to draw amazing things seemingly out of nowhere. talk about intense spiritual power!
I can only imagine that the music would be dramatic, funky, contain the contrast of minimalism (considering Miles' penchant for space) and indulgence (Jimi's hair-raising guitar busyness and histrionics), in short, powerful. Both artists were in a sonic transformational point in their carreers, especially Jimi, who was focusing on more playing than screwing the guitar.
Jimi pushed the limits of the power trio set up, making it sound so huge with the Band of Gypsies. My head goes crazy imagining what he'd sound like having Tony Williams behind him, as Jimi interacts uniquely on top of a drummer. And the thought of Jimi trading wailing licks with Miles trumpet, ahhhhhhhhhhhhhh! Imagine what they'd do to "All Blues"?
