Coming up in the mid-1980s New York City Hip-Hop era, R.A. The Rugged Man traveled from Long Island to Brooklyn to experience his favorite MCs. The friend of The Notorious B.I.G. and longtime collaborator of Havoc and Sadat X loved Hip-Hop’s history, and collected tapes and studied flows. The 20-plus-year vet showcases what he learned, as well as what he’s accomplished in his own career in “Definition Of A Rap Flow.”

The video features Cold Crush Brothers O.G./MC pioneer Grandmaster Caz, as well as appearances from Dinco D (Leaders Of The New School), Chill Rob G (Flavor Unit), Sadat (Brand Nubian), The Beatnuts, and others. Moreover, some awesome editing reworks everything cool about the ’80s (from Blues Brothers to “Pac Man” to Kangol fisherman buckets) in this self-directed video.

What’s more, R.A. (who’s been making some visuals for Talib Kweli and others lately) directed this dopeness himself. For the hardcore Heads, this effort is an homage to Biz Markie’s Goin’ Off joint, “Albee Square Mall.”
