March 29, 2003, DJ Shadow did a 2 hour mix on BBC 1 radio during a John Peel show. He used a Zappa sample in his mix.
The show was made available as a 2 CD set through his official fanclub in a limited edition of 1000 copies. Shortly thereafter, unofficial (bootleg) copies showed up, both on CD and on vinyl.
