Ever since April, Chicago's newest star, Chance the Rapper, has been performing a cover of the classic kids show "Arthur" with his band The Social Experiment. From Sasquatch Music Festival to Governor's ball, Chance has been performing the cover at several festivals this summer, and has caused a serious buzz around the new material. Earlier this week, Chance released the official track through Lollapalooza Music Festivals' website before he performed this past weekend. "Wonderful Day: Arthur" features more artists including Wyclef Jean, Elle Varner, Jesse Ware, and many more to provide additional vocals. You can check out Chance's new single after the jump, and let us know what you think about it.
