They made a CD entitled Rippin' and Rappin' and sold copies at their school (Highland Middle School). When he was in seventh grade, Harlow acquired a professional microphone and made his first mixtape, Extra Credit, using the moniker "Mr. Harlow". Harlow attended Atherton High School, graduating in 2016.
