Originally released in 2003 as a HipHopSite.com exclusive, Nastradoomus blends Nas acapellas from the 1999 Nastradamus album with instrumental beats produced exclusively by MF DOOM—many sourced from his Special Herbs Vol. 1 & 2. Licensed and pressed by bootleg-friendly indie labels like Rebound, this mashup double-album mixes iconic Nas vocals with Doom’s trademark sample-heavy, gritty production. It features highlights like “Life We Choose,” “Project Window,” “You Owe Me,” and “If I Ruled the World.” Though unofficial and never formally endorsed by either artist, the project became a cult classic in underground hip-hop circles.
