Scott Mescudi launched himself into the hip-hop atmosphere with 2008's A Kid Named Cudi. The landmark mixtape caught the ear of Kanye West, who signed the emo MC to his G.O.O.D. Music imprint. Blurring the lines between singing and rapping, Cudi's proper debut album, Man On the Moon: The End of Day, featured experimental production from beatmakers like Emile and Ratatat. To avoid being pigeonholed, Cudi keeps active with a host of side-projects, like the alt-rock-tinged WZRD.
