Chance the Rapper and Alec Baldwin were both in Chicago for the Young Chicago Authors event over the weekend, so they did as any—okay, nope, there’s no way we saw this one coming. Their meeting resulted in a freestyle collaboration in which Chance beatboxed and Baldwin rapped an excerpt of Carl Sandburg’s 1914 poem “Chicago.” Sandburg set Baldwin up for success, as Sandburg was reputed for his plain-spoken free verse.

Chance posted the video to his Instagram Sunday. To learn more about Young Chicago Authors, visit the non-profit’s website.
