Guillermo Scott Herren is a producer who has been based in Atlanta, Barcelona and New York City. Herren releases music under the aliases
Prefuse 73, Delarosa & Asora, Ahmad Szabo, and Piano Overlord, and is also part of the groups Savath y Savalas, Sons of the Morning, Fudge,
Risil, and Diamond Watch Wrists.
Herren began his career working in commercial studios in Atlanta. Vocal Studies + Uprock Narratives, his first album as Prefuse 73 -- after
lower-key releases as/with Delarosa, Delarosa & Asora, and Savath & Savalas -- not only buried but cut up and spliced voices as well as allowing
some more straightforward vocals from several MCs. The 2003 follow-up, One Word Extinguisher, carried on in a similar vein.
Surrounded by Silence, the successor to One Word Extinguisher, was released in 2005, featuring collaborations with rappers Ghostface and
Aesop Rock, plus Blonde Redhead and EL-P. Three months later, an EP of recordings made with the band the Books appeared, titled Reads the
Books. The next Prefuse record, 2006's Security Screenings, was relatively light on collaborations; it featured only two guests, Four Tet's Kieran
Hebden and TV on the Radio's Tunde Adebimpe. Preparations, featuring Battles drummer John Stanier on one track, followed in 2007, and
Everything She Touched Turned Ampexian appeared in 2009. Herren focused on collaborative projects in 2010, flexing his production muscles via
dates, remixes, or cameos with everyone from Zach Hill (Diamond Watch Wrists) to Oneohtrix Point Never to TV on the Radio. His 2011
production The Only She Chapters continued the familial feeling, with a wealth of features for female vocalists.
A few years later, newly inspired, Herren returned to the Prefuse 73 moniker with a flurry of releases on Temporary Residence Limited -- an outlet
endorsed by friends Nigel Godrich (Ultraísta) and Hebden -- beginning with the 25th entry into the label's Travels in Constants EP series. The
album Rivington Não Rio, featuring guest appearances by Busdriver, Rob Crow, and Helado Negro, was flanked by the EPs Forsyth Gardens and
Every Color of Darkness. During that summer and fall, Herren recorded several sessions with MC Michael Christmas under the name Fudge. The
duo's playful debut full-length, Lady Parts, arrived on Lex Records in September of 2016.
