When two MCs with the caliber of Pharoahe Monch and Black Thought collaborate, it's always a treat for hip-hop fans. That's exactly the case on the latest Monch single 'Rapid Eye Movement' featuring The Roots frontman. This Marco Polo-produced track will be featured on Monch's upcoming album, 'P.T.S.D.,' as the former Organized Konfusion member tackles the subject of post traumatic stress disorder.

As you would expect from these two lyrical heavyweights, some amazing bars are spit on this high energy track. "So when the beat intensifies / I become emotionally desensitized / like once I slapped a rapper with mace / Then I spit acid in his face after he rinsed his eyes / No wait, I actually grew five times my size, grabbed Mase by the thigh and slapped a rapper with him / Now that's practicing sacrilegious activism / Attack is for battle and practical rap with wisdom," Monch rhymes.

Black Thought is not one to get outdone though. "My psychiatrist waive the doctor fees / When I wave the pistol and say listen quick, watching me so I can breathe / National association for the advancement / Of drugs for performance enhancement / And it's tough taking so many chances / But I've been a bad seed from the womb, they call me ovary cancer / And I got an ugly heart, although I'm totally handsome," he raps.

Pharoahe Monch's fourth solo album, 'P.T.S.D.,' will be in stores April 15.
