Killer Mike and El-P form the group Run The Jewels. Their first project together was an indie fan favorite. The two are working on their second album as a group and they’ve brought in some big names to help make their new cypher complete.

Stereogum is reporting that from the looks of Instagram, that Rage Against The Machine frontman Zach De La Rocha will be making an appearance as well as drummer Travis Barker.

Neither name has been confirmed as of yet.
