Run The Jewels performed on The Late Show with Stephen Colbert along side TV on the Radio. Just two days after Kendrick Lamar gave his stellar performance of a four-song medley that included “Wesley’s Theory,” “Momma,” “King Kunta” and “u,” RTJ brought the stage down last night (Sept. 15) and performed "Angel Duster" off their latest album Run The Jewels 2.

"Tonight's musical guest is so hip, their backup band is TV on the Radio," Colbert said while introducing the duo. Killer Mike and El-P plus TV on the Radio were a perfect fit. With the American indie rock band supplying the instruments, the energy of the performance could be felt from beyond the stage. The intense performance reached its peek at the final chorus. It's beautiful to watch.

As the music faded out, El-P said, "To Desiree Zondag and Ikey Owens, we love you and miss you" as photos of the two appeared on the Late Show screens. Owens, Jack White's touring keyboardist who appeared on the Run the Jewels 2 version of "Angel Duster," died of a heart attack in October 2014. Zondag, a Los Angeles costume designer, died Sept. 10 in a surfing accident. Watch the performance above.

RTJ is in the process of recording an album comprised entirely of cat sounds. The LP is a remixed version of the duo’s Run The Jewels 2 album that dropped last year. El-P of Run The Jewels announced that Meow the Jewels will drop in September. Meow the Jewels was funded through Kickstarter by fans and is being made solely for charity.The album will be released for free, as well as a limited deluxe edition vinyl. Fans will have the opportunity to listen to the project via streaming services. So far we’ve heard a preview of the Alchemist-produced record “CREWON,” another track titled “Angelmeowster” that is produced by Dan the Automator and “Meowrly,” which is produced by Boots. Zola Jesus, Just Blaze, Baauer and Portishead’s Geoff Barrow are also contributing to Meow the Jewels.
