Kool Keith
After releasing only one album on a major label, Black Elvis/Lost in Space, Kool Keith returned to independently releasing music. He worked alone  and with groups such as Analog Brothers, Masters of Illusion, Thee Undatakerz and Project Polaroid. Kool Keith has also made guest appearances  with Peeping Tom and Yeah Yeah Yeahs. The Prodigy's hit "Smack My Bitch Up" was based on Kool Keith's voice saying "Change my pitch up. Smack my bitch up."
