Originally posted as a pre-order offering for their seismic sophomore album Run the Jewels 2, the group jokingly promised to remix the album using only cat sounds in exchange for $40,000. An enterprising fan called their bluff via a highly publicized and successful Kickstarter campaign which exceeded its goal. Instead of backing down from the absurd premise, El-P and Killer Mike have rose to the occasion, assembling a stable of immensely talented producers (including El-P, Just Blaze, Prince Paul, Geoff Barrow of Portishead, Massive Attack, The Alchemist, Zola Jesus, Nick Hook, BOOTS, Dan The Automator, and more) to help deliver the goods.
