Both of them were rapping and Kadafi's Godbrother was the notorious rapper Tupac Amaru Shakur. Kadafi's mother, Yaasmyn Fula, told Tupac about Beale. She told him how he witnessed his parents being murdered and it made him cry. He felt he had to met Beale. They met and Beale joined their group, Dramacydal.
