Chief Keef's been on fire throughout 2017, and he hasn't shown any signs of letting up any time soon. One day after unveiling his new song "Mailbox," which is the first single from his forthcoming album, The Dedication, the talented Chicago artist teases a new collab between himself and Lil Uzi Vert.

In the clip, which appears to have been posted as a story on one of his social media accounts, we see Uzi rocking out to his own Auto-Tune-laced vocals and a hard beat. For his part, Keef looks about as jovial as can be as he sips a drink, smiling when he's not sipping. His vocals don't sound like they've been coated with any noticeable effects, so it looks like Keef's leaving the crooning to Uzi.

While Keef doesn't offer details on the collab between himself and Uzi, it feels sort of safe to assume the track will pop up on The Dedication. After all, why wouldn't he want to bring out the big guns for his newest album? And make no mistake, after his Luv Is Rage 2 album sold 135,000 copies in its first week of release, Uzi could definitely be called a "big gun." It does seem like Pierre Bourne produced the track, though, as he said he was in the studio with Keef and Uzi the same night.

We don't hear much of the track, but it's clear Keef and Uzi match up pretty well on wax. Both have sort of pushed the limits of Auto-Tune and the way it can enhance music, so anything they do together should be fairly cohesive.

Check out Keef's preview in the video below, and watch him listen to the finished track in the whip too.
