Chief Keef has linked up with budding Atlanta super producer Metro Boomin' on a new project. Sosa recently announced the two have put together an EP which will be released next week. Taking to his Twitter account, Keef posted, "Peacocks, Peacoat's, Flavor, & Paper! The EP prod by @MetroBoomin Coming soon!!!! Halloween......"

We might have already gotten the first taste of the project. Last month, Keefy released the song "Murda Mook" featuring Sean Kingston. The song is produced by none other than Future's go-to-guy, Metro.

This adds to the list of projects dropping on Oct. 31. Young Thug is dropping a solo mixtape, Slime Season 2, as well as a collaborative mixtape with the Migos titled MigoThuggin. Sheek Louch is also dropping a mixtape that day called, Gorillaween. You will be able to download Vado's latest mixtape Slime Flu 5 then, as well.

Keef continues to roll out new music. Earlier this month, Sosa dropped three new tracks, “Don’t Love ‘Em,” the Tadoe-featuring “Cabbage” and “BIH.” The songs were part of a four-track EP released by DJ Hustlenomics titled Massacre. In September, Keef put out his long-awaited sophomore album Bang 3. He also dropped a joint mixtape with DP Beats titled Almighty DP. It looks like the Los Angels life is good for the Chicago rapper's work ethic. Metro, of course, is fresh off executive producing Drake and Future's mixtape, What A Time To Be Alive as well as Future's latest album Dirty Sprite 2.
