Donnie Trumpet & the Social Experiment released its much anticipated debut album Surf via iTunes on Thursday night for free—and as expected, it prominently features Chicago rap wunderkind Chance the Rapper, along with a stacked list of collaborators including Busta Rhymes, Janelle Monáe, J. Cole, Big Sean, Migos’ Quavo, B.o.B. and Erykah Badu.
The 22-year-old Chance broke through two years ago with his second mixtape, Acid Rap, and has been hyping Surf since October—but the record isn’t his, and that’s an important distinction to make. Where Acid Rap relied on the types of chipmunk-soul samples that defined fellow Chicagoan Kanye West’s early work, Surf deals in peppy pseudo-jazz, mostly recorded live by Donnie Trumpet, the stage name of trumpet player Nico Segal, and the Social Experiment, a group of which Chance is a member.
“If they only wanna listen to the songs with Chance The Rapper, they’re gonna have to listen to the whole project cover-to-cover because I’m not gonna tell them which songs [he’s on],” Segal said in a Fader story earlier this year. “The important thing is just to listen. Listen to the music, then send it to your grandma.” Segal’s old group, Kids These Days, included rapper Vic Mensa and performed in the same Chicago scene as Chance before it broke up in 2013.
