After teasing a new album extensively on Twitter, Killer Mike and El-P have finally announced the next Run the Jewels album. The follow up to last year's Run the Jewels is called RTJ2, and it's out October 28 via Nas's imprint Mass Appeal. That's the full version of the previously previewed track "Blockbuster Night Part 1", above.

It was previously hinted, and now confirmed, that the album features contributions from Rage Against the Machine frontman Zack de la Rocha and Blink-182 drummer Travis Barker.

Unlike RTJ1, the new one will also get a wide physical release on CD and LP. In a press release, El-P said, "We can make no promises about the safety of any animals involved in the creation of this record." Killer Mike said, "It is the best rap group album since RTJ1!"

On September 15, Run the Jewels will release a new track via the Adult Swim Singles Series.

Killer Mike has been in the news a lot recently, speaking out against the death of Michael Brown and the abuse of police power in Ferguson, Missouri.
