sigur ros can definitely be Soft&Complex,,, his/their BBCradio1 performance of ''weirdos'' was what i would loop on my head-phones for my most recent(6yearsago?!?) DMT 'sessions'
Coltrane is the man, and gets and gives nods... for sure.
but much different then Bitches-Brew.
i may actually go to Coltrane more for straight Jazz, and trust any quartet ensemble he is in.
Bitches-Brew is jazz, but i would warn people, that its actually Fusion... many Jazz listeners may not take this feel on so well.
what happened with this album, was that Miles took these great established musicians, and dropped them on new to them electric keyboards/hammond organ, or electric guitars with lots of effects. many relative changes in the musicians training, and practice that caused them to have to relearn their instrument, force through, disassociate and this is very striking and apparent through out this album -- it is the way Miles Davis directed and manipulated this "fugue" of Jazz, and it couldnt of been done any other way i dont believe; it had to be a natural process; a rebirth which cant honestly be done knowingly.
hmm ramble///
