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.

The Champion Sound Instrumentals have also been released. Madlib remixed several Jaylib tracks in 2007, which was issued as Champion Sound: The Remix. The album and the remix were also released as a double cassette.
