Killer Mike and El-P are the rap duo known as Run The Jewels. Their latest album ‘Run The Jewels 2‘ is under Mass Appeal Records label and boasts 12 tracks of straight raps with gritty lyrics over grimy, aggresive beats. Features include Travis Barker, Gangsta Boo, Zack De La Rocha, Diane Coffee, and more. Run The Jewels initially began as a collaboration announced by Cartoon Network’s executive, Jason DeMarco, in 2011 for music to be made to be featured on it’s Adult Swim. Since then the rap duo continued to work together, most notably on Killer Mike’s studio album ‘R.A.P. Music’, and have perfected their sound.
