Das EFX is an American hip-hop duo comprising emcees Dray and Skoob, whose innovative stream-of-consciousness delivery revolutionized rap's lyrical landscape in the early 1990s. Rising to prominence through their association with EPMD's Hit Squad, the group distinguished themselves with intricate, fast-paced rhymes that blended invented vocabulary with sharp pop culture references, creating a signature style that influenced generations of hip-hop artists.
The duo's approach to production and flow—layering complex wordplay over dynamic beats—bridged hip-hop and electronic music sensibilities, making them essential fixtures in the era when rap and dance music began converging. Their work remains foundational to understanding how lyrical innovation and rhythmic experimentation shaped modern hip-hop production and electronic music aesthetics.
