Brace yourself: Photos just hit the Internet suggesting that Killer Mike and El-P—who record together as Run the Jewels—are working on new material… with Rage Against the Machine frontman Zack de la Rocha and Blink-182 drummer Travis Barker.

Barker posted a photo of the musicians in the studio on Instagram with the caption, “In the studio listening to  #RunTheJewels2 with@killermikegto #ELP and #ZackDeLaRocha Nuthin short of amazing #EarCandy #RunTheJewels#GoodMusic.” 

Killer Mike, El-P, de la Rocha, Barker and Yak Ballz can be seen in the image. Check it out above.

El-P also posted an Instagram of just de la Rocha with the caption, “Yes it really is happening. #RTJ2" and later tweeted, "I can confirm that Zack is on the record. Nothing else should be assumed from a photo. OR SHOULD IT???? no, not really. OR AM I????? wait.."

So while Run the Jewel are definitely working with the Rage rapper, Barker's presence on the sequel album to Run the Jewels is still speculative. 

Now the question becomes... Is the world ready for a rap rock revival?
