It seems like everyone's cutting a rap album these days.

Not even a stellar-mass black hole could keep MC Hawkings, "the undisputed king of theoretical gangsta astrophysics," from busting mad beats.

Tracks on his latest CD, A Brief History of Rhyme, include such classics as "E=MC Hawking," "All My Shootin's Be Drivebys" and "A Brief Dissertation on Gravitational Entropy, Quantum Cosmology and the Anthropic Principle."
