Loco is the fourth mixtape by Memphis rapper BlocBoy JB. Released on March 12, 2017, the project is again hosted by frequent collaborator and producer Tay Keith, and serves as the follow-up to his December 2016 tape Who Am I 2. Boasting 13 tracks and no features, Loco includes the track “No Chorus Pt. 9,” the ninth installment of Bloc’s popular “No Chorus” song series. The tape was his last to not be released on streaming services, as June 2017’s Who Am I 3 marked his ascension into the mainstream hip-hop scene.
