I think true invention is rare, and when it happens, other artists turn that invention into a new genre and set of conventions, and the cycle begin again.
Most of what is considered innovative in music is actally recontextualization, ime. Bjork smashing together techno, jazz, pop, classical minimalism, etc. Prince fusing new wave and funk. David Bowie’s career. Hell, the whole genre of hip-hop is based on recontextualization.
(It’s still work to make that recontextualization make sense, otherwise you’re just making novelty music or culture vulturing)
