As his namesake suggests, MGK is known for spitting bullets. The Ohio native first turned heads with his rapid-fire delivery and dynamic stage performances-and since then he's been stacking up the accolades. MTV named him the Hottest Breakthrough MC of 2011; he won the MTVu Breaking Woodie Award; he was featured on the latest XXL Freshmen cover; and he may have the greatest name for a home recording studio ever-The Rage Cage. Now the Wild Boy is backed by Bad Boy Records, and his fans are patiently waiting for his debut album Lace Up to drop this summer.
