I came across this documentary about David Choe after seeing that he attended the Comic Con event this year promoting his new dvd. Most people would not be familiar with his work but you would be surprised if i showed you some examples that you might actually know them.
The JayZ / Linkin Park Album cover.
One of his many Giant Robot covers.
David colab with Scion on the Monster XB.
Here is a link to the documentary about David below. You will see how dark he is and how after a stint in Jail he took a new direction in his life. Watch out for the bit with Sean Parker of Napster/Facebook fame when he gets David to design his new offices and doesnt get what he wanted.
