Das EFX is an American hip hop duo. It consists of emcees Dray (also known as Krazy Drayz, born Andre Weston, September 9, 1970) and Skoob (also known as Books and Boogie Bang, born William "Willie" Hines, November 27, 1970).
As their career progressed, Das EFX's once-distinctive and unique lyrical delivery was imitated by several other artists and became more commonplace.
