J Dilla and Madlib are Jaylib. It started with Madlib recording verses over J Dilla beats for himself to hear and scrawling "Jaylib" on the homemade CD. Word of this made its way to Detroit and J Dilla suggested they do it "the right way." Champion Sound was recorded in entirely separate cities 2002-2003, with Dilla recording over Madlib beats in Detroit, Madlib recording over Dilla beats in Los Angeles.
