At Jones College Prep High School, some of his teachers ridiculed his aspirations to become a musician. In early 2011 during his senior year, following a 10-day suspension for marijuana possession on campus, Bennett recorded his first full-length project, a mixtape entitled 10 Day (also known as #10Day). In December 2011, he released a song titled "Windows", and publicly announced his 10 Day project. In February 2012, Bennett was highlighted as one of Complex magazine's "10 New Chicago Rappers to Watch Out For". Bennett says he spent "about eight months recording, writing, and making connections off of the hunger to put out something". Bennett released the mixtape on April 3, 2012, and it has since been downloaded over 500,000 times via mixtape-sharing site DatPiff. The mixtape was well-received locally and helped Bennett make connections with producers such as Chuck Inglish, Kenny Jame$ and Blended Babies. The mixtape also grabbed the attention of Forbes magazine, which featured it in the publication's Cheap Tunes column.
