From the Madlib Medicine Show #11: Low Budget High Fi Music here is a track from Madlib & J Dilla from their never-realized second album.
Jaylib was formed in 2002 as Madlib & Dilla recorded separately in Los Angeles and Detroit. Their one album, Champion Sound, was released in 2003. When J Dilla moved to Los Angeles, he, Madlib and J Rocc began doing shows together as Jaylib, performing together for the first time at the Madvillain record release party in April 2004.
Madlib and Dilla collaborated primarily through the exchange of beat tapes, occasionally reworking each others material, or chopping the same beat in a kind of recorded call-and-response.
