How was the development of jazz-related to modern musical genres such as hip-hop and rap

Jazz-Rap was an attempt to fuse African-American music of the past with a newly dominant form of the present, paying tribute to and reinvigorating the former while expanding the horizons of the latter. While the rhythms of jazz-rap came entirely from hip-hop, the samples and sonic textures were drawn mainly from cool jazz, soul-jazz, and hard bop.
