When Billboard ran an article with the headline "Exclusive: Chance The Rapper Reveals New Album, Surf" in October 2014, it seemed like his fans' thirst was soon to be quenched. And it will be. Except Surf is not a Chance The Rapper album. It's not even a rap album, really. It's the sprawling debut by Donnie Trumpet & The Social Experiment—The Social Experiment being the four-member songwriting and production unit that began as Chance's backup band on his 2013 tour of the same name. Donnie Trumpet, a 21-year-old born Nico Segal, is the member of this collective who—you guessed it—plays the trumpet. Chance is another member, but, notably, he's just another member. He's buried himself in a group setting, deferring a shot at becoming a more-than-reasonably-famous rapper in favor of an uncentered, cross-genre collaboration with his friends.
