Early demo recordings of the iconic Hip Hop album! In November 2002, the first demo sequence of Madvillainy leaked online.

The tracks contained early vocal cuts from Madlib's Bomb Shelter studio. It may have been unfinished, but fans understood that this was a hip-hop album unlike any other.

DOOM rerecorded vocals - alluding to the leak on "Rhinestone Cowboy" - and Madlib added new beats and changed up the sequence.

Leaks could kill an album's momentum in the early 2000s, but the demos only whetted fans' appetites; when Madvillainy came out in 2004 it was "One of the most anticipated released in underground rap history," according to Pitchfork.

Madvillainy is now regarded as one of the greatest hip-hop albums of all time."
