Prefuse 73 is the alias of Scott Herren, an experimental hip-hop producer whose material often features MCs buried in the mix to become more a part of the sonic texture than a focal point. Herren began his career working in commercial studios in Atlanta, but later went on to more experimental work. His first record under the Prefuse name, Vocal Studies + Uprock Narratives, not only buried but cut up and spliced raps as well as allowing some more straightforward vocals from several MCs. The 2003 follow-up, One Word Extinguisher, carried on in a similar vein. That same year, Warp released Extinguished: Outtakes -- a fascinating EP of beats and samples that ran through 23 tracks in about 35 minutes.
