MF Doom is the man in the iron mask. The most mysterious figure in hip-hop has also become one of the most popular, supplying beats and rhymes for Gorillaz, De La Soul, Madlib, Danger Mouse, and Wu-Tang Clan, and drawing praise from heavyweights like Just Blaze, Nas, and Mos Def along the way. Since 2002, MF Doom has released numerous volumes of Special Herbs, one of the longest-running instrumental series in hip- hop history. With obscure loops and dusty samples galore, Special Herbs is a must-have for any MF Doom fan or hip-hop head. MF Doom's Special Herbs series is now available on cassette for the first time in a special 5x cassette box set!
