Project Pat began his career with appearances on his brother Juicy J's early releases with DJ Paul in the early 1990s. After serving several years in prison for robbery charges and disappearing from recording, he re-emerged in 1999 with the solo album Ghetty Green, released on his brother's Hypnotize Minds label. He became an unofficial member of Juicy and Paul's newly established group Three 6 Mafia, and first gained mainstream attention when he provided the hook for the group's hit single "Sippin' on Some Syrup" in 2000.
