If you listen to the first 33 minutes of Bob James' "Take Me to the Mardi Gras," you will find basically the history of hip-hop. That small (indeed tiny) space of time takes you from the Crash Crew's "Breaking Bells" (1982) all the way to Missy Elliott's "Work It" (2002). LL Cool J's groundbreaking "Rock the Bells" is in there, and so is NWA's "Straight Outta Compton." And if you turn to Bob James' "Nautilus," you find the materials for the greatest (most spaced-out) track in the history of hiphop, Eric B. & Rakim's "Follow the Leader" (1988). Though Bob James began his career in free jazz, hip-hop sampled (and continues to sample) his marvelously smooth jazz period in the 1970s. Going to this show is like going to the temple of hip-hop.
