Living hip-hop legend KRS-One is prepping his twentieth (!) studio album, Just Like That, for an early 2012 release. But before he drops some new knowledge on us all, the Teacha is taking us on a trip down memory lane. With a green screen behind him, KRS travels throughout New York City while reminiscing over a classic boom-bap beat on "Just Like That." It makes for a great way for the youth to learn a thing or two about an artist who paved the way for so many hip-hop acts over the years. And for the rest of us, well, it's another reminder that the genre doesn't necessarily have to be a young man's game. Watch the video below.
