Das EFX appeared on the rap scene in 1992 with their platinum-selling album Dead Serious, which combined elements of hip-hop and hardcore rap with a novel, stammering vocal style and quickly established the East Coast group as versatile, freewheeling, and original. Skoob and Drayz are inspired by a wide range of music beyond the hip-hop and rap realm and cull their riffs from favorite rhythm and blues, jazz, reggae, dancehall, and classical music pieces. Some of the other recording acts sampled in Das EFX songs include Kool & the Gang, James Brown, and the Beastie Boys.
