There is something very powerful about nostalgia. There is also something about encountering people who know the same kind of obscure crap that you like. Quasimoto (aka Madlib) does both for me in this video.
The song itself is basically a braggart's anthem that "I know rap, my man." And the video is strictly a litany of half-second clips of old rap videos, picturs and clips, some recognizable (Fred Flintstone scratching is a trip), some completely obscure (Maestro Fresh Wes, Son of Bazerk, the Mr. T "Treat Your Mother Right" song, Freshco & Miz). It's a combination of highbrow and lowbrow that makes for sensory overload and a Pavlovian orgy of images that make me want to break out all my old tapes.
