Jazz stopped being creative in the early '80s. After your acoustic era, where you had the likes of the Miles Davis Quintet, when it gets to the '70s it started being jazz fusion where you had more electronic stuff happening, then in the '80s they started trying to bring back the acoustic stuff, like Branford Marsalis and the Wynton Marsalis & Eric Clapton sextet. It started dying down from there. Miles was still around in the '80s and he was still being creative; he was playing Michael Jackson songs and changing sounds, but a lot of people were still trying to regurgitate the old stuff.
