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.
