During his four years of school, he worked with a variety of local acts including Big Bud,[7] The Strugglazz, Shorty Roc, Lil Po and Dieng Breed.

Until the band's dissolution in 2011, they put out seven EP's and one full-length album,[8] cutting out their own niche of pop rock, hip hop and electronic music.

That year, Miller met rap artist Freddie Gibbs through friends Josh The Goon and The Knux, who were labelmates with him at Interscope Records.

The two started working together and their relationship developed into a slew of songs that would be released on Freddie's subsequent mixtapes, MidwestGangstaBoxFrameCadillacMuzik, The Labels Tryin To Kill Me!
