That sounds like it could be awesome. The closest thing I can think of would be Malignant Narcissism by Rush. ✌️

IMHO jazz is listening. In composition it's about listening to the movement in the harmony and melody, and how they support each other.  In performance it's about listening and reacting to the other musicians in the band.  In improvisation it's about listening to where things are going, and what each musician is doing, and how you support that together.  It's hard to separate jazz from improvisation - that's been a fundamental aspect of it since its inception.  Prog and metal don't typically have as much of an improvisation component, but of course anything can be done.  Some bands like Umphrey's McGhee have some heavier songs and certainly improvise, but it's more of a rock context than jazz.  Improv alone doesn't make something jazz, nor does more complex harmony.
