There's a slim chance you'll actually see the real DOOM if you hit up one of his live concerts, but his music is still making plenty of impact off-stage. After he dropped the MF from his name a few years ago, he came through with the well-received LP, Born Like This. In the time since, he's released a collaborative album with producer Jneiro Jarel, which once again showcases him rapping with top-notch wit and precision.

Next up: Swift & Changeable, the long-awaited album he's releasing with Ghostface Killah. There's another Madvillain project on the way, too. Even though DOOM remains relatively obscure, his continues to hit hard.
