Well, we didn’t see this one coming.

Chance the Rapper has collaborated a lot lately with several artists, one of the artists being Lil B.

According to both artists Instagram profiles, the B and Chance just made music together. That’s right, an album in studio on Saturday night. (July 18)

Could this be just a publicity stunt for the Chi-Town headlining at Pitchfork Music Festival on Sunday night, who knows?

And although, there is very limited revealed information confirming if this album will be released, if you happen to like Based music, then this might be something to be on the look out.

We shall wait and see what this is all about, so we will keep you posted as this topic develops.
