Date: Late 1980s

Large Professor served as more than just a producer for Nas. In addition to producing a bunch of tracks for Nas' debut, Illmatic, including "Halftime," "One Time 4 Your Mind," and "It Ain't Hard to Tell," Large Pro was also a mentor to Nas and, more importantly, one of his first friends in the music industry. You could argue that without Large Pro, there might not be a Nas right now. And you might just be right.
