Steve Lacy - Dark Red
Steve Lacy has racked up some serious credits in his 18 years of life. On top of this very tidy solo work, he is guitarist and vocalist for The Internet, was nominated for a Grammy as Executive Producer of their album Ego Death, and accidentally produced Track 7 PRIDE. from Kendrick's new album DAMN.
He also produces everything on his jailbroken iPhone.
Wired did an awesome piece on Steve here if you feel like reading up on him.
