Guest List: Bun B

As one half of UGK, Bun B toiled away on the southern underground for years before JAY Z thrust his rapid-fire flows into the mainstream spotlight in the late-'90s. Since then, the Port Arthur man's verbals have been in demand, with him lighting up rap tracks for Drake and Ludacris, and bringing his street smarts to R&B moments from Beyoncé and Mya.
