He released a remix of Asher Roth's "She Don't Want A Man", which received minor airplay on Los Angeles radio. The positive feedback inspired him to create a mixtape, which would be known as The First Flight.
In 2010, he released a music video of him rapping over the music for Nas's single "Made You Look", which ended up gaining over 2 million views on YouTube. Soon afterward, he signed a record contract with Atlantic Records and released the mixtape Airborne.

In May 2011, Simmons released his debut single for Atlantic Records, entitled "Copy, Paste.". He performed the single at the
BET Awards of 2011, which was also his first televised performance. Simmons explained that "Copy, Paste’ is just for people that are original, people that are innovators, people that just do their own thing".
