Good point about 'Black Star' I agree that it encompasses many styles. Bowie always pushed the limits of genres and always seemed to reinvent himself and his music. We need to discover the other Bowie's of the world.
Massive Attack is another good example that Warren mentioned.
I remember hearing the band Us3 in the 90s and thinking how brilliant their music was blending hip/hop and jazz. They had one big hit and unfortunately the hip/jazz didn't quite take off back then. I still think those are two styles that can mix well.
