This Halloween is going to start with a big musical surprise.

21 Savage, Offset and producer Metro Boomin will drop the aptly named Without Warning album at midnight tonight.

Metro Boomin has been behind some of 21 Savage's ('No Heart') and Offset's ('Bad and Boujee') biggest moments, so this one has a lot of potential.

Are you hype for the second big Atlanta collab of October?
