Cannibal Ox is a New York hip-hop duo made up of Vast Aire and Vordul Mega, with El-P, the founder of the Definitive Jux label, handling the lion's share of production. Their first record,The Cold Vein, has been heralded as a major turning point in both hip-hop production and lyrical organization. Several notable guests appear on the album, including C-Rayz Walz, L.I.F.E. Long, Alaska (of Hangar 18), Cryptic One and El-P himself, while Vordul's baritone and Vast's nasal-y styles connect the eclectic project together.
