Das EFX is an American hip hop duo. It consists of emcees Skoob (also known as Books, born William “Willie” Hines, November 27, 1970) and Dray (also known as Krazy Drayzy, born Andre Weston, September 9, 1970). They rose to popularity in the early 1990s due to their affiliation with EPMD’s Hit Squad and the duo’s stream of consciousness lyrical delivery, which became one of the most influential lyrical styles in hip hop music during the early 1990s. Their style combined nonsensical lines with a fast-paced flow (that included words that end with “-iggedy”) and numerous pop culture references.
