It's been a while since we've heard new music from Chief Keef, with the Chicago rapper previously claiming he had retired from music.

In fact, the only new music we heard from Keef in 2016 was a featured verse on Machine Gun Kelly's single "Young Man." However, now we are officially in 2017, Chief Keef has dropped his first full length project since 2015's Finally Rollin 2.

Sosa has returned with Two Zero One Seven​, a 17 track mixtape with no features and production from Lex Luger, Leekeleek, Young Chop and Keef himself. 

Although he had a relatively quiet 2016, Keef performed last July at the Pigeons and Planes stage at ComplexCon, turning the stage into a full blown party. 

Check out the new mixtape below.
