Acid Rap

Acid Rap is the second mixtape by American rapper Chance the Rapper. The project is a sequel to his debut studio mixtape, 10 Day. The mixtape was recorded from 2012 to 2013 in Soundscape, Force One, Seven, and Classick, all studios based in Chance's home city of Chicago. The mixtape was produced by Nate Fox and Peter Cottontale (later of Chance's group the Social Experiment), Cam O'bi, Stefan Ponce, Two-9 member Ceej, Nosaj Thing, DJ Ozone, Ludwig Göransson, Odd Future member Brandun DeShay, Blended Babies, Jake One, and Na'el Shehade. The project features artists such as BJ the Chicago Kid, Lili K., Nosaj Thing, fellow Savemoney member Vic Mensa, Twista, Noname, Saba, Childish Gambino, Action Bronson, and Ab-Soul.

Before the mixtape was released, it was accompanied by two singles: "Juice" on January 31, 2013 (doubling as Chance's debut solo single) and "Acid Rain" on February 22, 2013. The project was later released on April 30, 2013, as a free digital download. After release, the mixtape charted at number 5 on the Billboard 200, number 3 on the Top R&B/Hip-Hop Albums chart, number 2 on the Top Rap Albums chart, and number 18 on the Billboard Canadian Albums chart. In July 2013, the mixtape reached number 63 on the Billboard Top R&B/Hip-Hop Albums chart due to bootleg downloads on iTunes and Amazon not affiliated with the artist.

The mixtape has been certified "diamond" on the mixtape site DatPiff for garnering over 1,000,000 downloads. It was re-released on streaming services on June 21, 2019, alongside his previous mixtape 10 Day. A 10th anniversary "Complete Edition" was released soon after, including the full version of the lead single "Juice", which previously had not been available for streaming due to sampling issues.
