This past week, we got a new Kendrick Lamar project, Untitled Unmastered. It featured eight leftovers from the To Pimp A Butterfly sessions. On the project, Lamar works with Nard & B.  But those are not the only Atlanta producers he's been in the studio with.

During an interview with BBC and Benji B, Metro Boomin' let it be known that he and Kendrick recently hit the studio together. No completed music came out of the session, but Metro says that Lamar took a few beats home with him.

In the interview, Metro Boomin' also discusses upcoming work with Big Sean, his relationship with Future, and more. Listen to it below.
