Run-D.M.C.'s Jam Master Jay is one of the most important DJs in the history of rap music. Though he died in 2002, his memory is carried on in part by his son T.J. Mizell, who also mans the decks. Recently, Mizell performed a rogue set on a Brooklyn-bound J train from Manhattan, video of which you can see above.

In the clip, Mizell and crew hop onto a subway car where he blends and chops a few records as the train crosses the Williamsburg Bridge into Brooklyn. The video is poignant and entertaining, partly because those actually present on the train seem to be paying Mizell little-to-no attention. New York City, folks.
