Chance the Rapper has been teasing his new mixtape for what seems like forever. His two previous mixtapes (2013's Acid Rap and 2012's 10 Day,) were both released in the month of April and it looks like his new one will come during this month, as well. During a surprise concert in New York, Chance declared that the new collection of music will definitely be out before the month's end. It will follow collaborative effort Surf, made alongside his Social Experiment band, and Free (Based Styles Mixtape) with Lil B.
