Chance the Rapper is the most famous independent rapper out right now - having secured three Grammy nominations with his version of a mixtape last year. Now that fans are waiting for new music from rap's Mr. Congeniality, Chance is busy helping support independent artists with the same potential to be superstars. Like Toronto's Daniel Caesar.

During a visit to The Late Show with Stephen Colbert, Chance the Rapper invited the rising R&B artist (who recently dropped his stunning debut album Freudian) to take the stage with him to unveil a brand new song they had just written. The song is so new, they don't even have a name for it yet. Watch their incredible performance below.
