In the above clip, Waah Dean takes Vlad through the wildly successful first phase of DMX's career. X had two albums go number one in the same year, and, like the Ruff Ryders founder said, "It's once you get on, how long can you stay on." Dean also talks the iconic "Flesh of My Flesh, Blood of My Blood," album cover, and the fabled Jay Z-DMX battle that took place in the Bronx. Watch above.
