Das EFX is an American hip hop duo.[2] 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).[2] They named themselves "DAS" standing for "Dray and Skoob" and "EFX" meaning "effects". They rose to popularity in the early 1990s due to the duo's stream of consciousness lyrical delivery, which became one of the most influential lyrical styles in rap music at the time;[1] as well as their affiliation with EPMD's Hit Squad. Their style combined intricate rhymes, sometimes mixed with made up words (especially ending with "-iggedy"), delivered with a fast-paced flow and numerous pop culture and hip hop culture references.[2]
