Chance The Rapper has been riding the crest of his new collaborative mixtape Surf for most of this year, but it seems like the tireless wunderkind never lets up. Instead of resting on his laurels, Chance put out another fully freestyled mixtape collaboration with Lil B and is apparently hard at work on his third solo mixtape. At a performance on Saturday night at Austin’s legendary Stubb’s barbecue joint, he debuted a joyous new song that unsurprisingly features plenty of brass, his signature squawk, and wordless melodies. Oh yeah, and plenty of quick, clever wordplay, including further teasing of a new release with lyrics like “new album alert.” It sounds like a liquid jazz song with Lion King references — something only Chance could pull off. At the end of the untitled track he tosses off another clue about the song’s place in his discography: “third mixtape.” His first tape #10Day came in 2012, followed by his breakout Acid Rap in spring of 2013.
