Run the Jewels release 'Rubble Kings' for free

The theme from New York documentary "Rubble Kings" has been released as a free download by rap duo Run the Jewels and label Adult Swim.

The film's soundtrack is due October 30 through Mass Appeal Records, and features appearances from Bun B, Ka and Roxiny and more, with excerpts from its score provided by Run The Jewels collaborator Little Shalimar.

Documentary director Shan Nicholson was nominated for the Metropolis Grand Jury Prize at DOC NYC 2014, and his feature follows 1970s Bronx icons the Ghetto Brothers gang and their inner-city vision for social, educational, and politcal engagement, served with a generous side of funk-powered block parties.

New York based Run The Jewels formed in 2013 and both debut album "Run the Jewels" and its 2014 follow up "Run the Jewels 2" were very well received.

The "Rubble Kings" single is released as part of a 19 week Adult Swim promo. Like its predecessors, it can be downloaded for free from adultswim.com/singles.
