22. 'Surf,' Donnie Trumpet and the Social Experiment
Fans may have been demanding a follow up to his 2013 mixtape Acid Rap, but Chance The Rapper has been winning in his career by doing anything but what's expected. That's the basis for Surf, the collaborative project from his band the Social Experiment, spearheaded by horn player Donnie Trumpet that is equal parts sprawling, fun, loose, emotional, jazzy and deep without losing its vigor throughout. There are plenty of heavyweight guest appearances -- Busta Rhymes, Big Sean, Quavo and Erykah Badu deserve special mention -- but it's the pure joy of songs like "Slip Slide," the ironic goofiness of "Wanna Be Cool" and the earnest charm of "Sunday Candy" that makes this project truly stand out. It's an avant-garde experiment masquerading as a hip-hop album, and in its experimentation it manages to exist in all genres and none at once.
