Krayzie Bone (born Anthony Henderson on June 17, 1974) also known as Leatha Face is a member of the rap group, Bone Thugs-N-Harmony. He, like his other group members, is known for his tongue-twisting rapid pace of delivery and his ability to create harmonic hooks within songs. He is the most laid back, versatile, and soft spoken member of Bone Thugs-N-Harmony letting his work show for itself.
DJ Scratch (born George Spivey) was introduced to EPMD by Jam Master Jay at the Run's House Tour after DJ K LA Boss left EPMD. Impressed by his skills, the two designated DJ Scratch as their official D.J. by their second album Unfinished Business in 1989. His presence was felt with his powerful cutting and scratching techniques that are heard on various tracks. Aside from scratching, on Business As Usual, he produced the track "Funky Piano", "Rampage" and in 1991 worked on a remix for "I'm Mad" off the Rampage 12" single.
