Surrounded by Silence, the proper successor to One Word Extinguisher, was released in March of 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 collaboration-free; it featured only two guests, Four Tet's Kieran Hebden and Tunde Adebimpe from TV on the Radio. Preparations, featuring Battles drummer John Stanier on one track, followed in 2007, and Everything She Touched Turned Ampexian appeared in early 2009. Herren focused on collaborative projects in 2010, flexing his production muscles via dates, remixes, or cameos with everyone from Zach Hill 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. Herren has also worked under his own name, and that of Savath + Savalas and Delarosa & Asora. ******
In 2013, Herren has launched a new label called: "Yellow Year" which starts with a monthly collaborative series entitled: "Speak Soon". Artists taking part include: Teebs, Nosaj Thing, Lapalux, Dimlite, Nathan Fake and more.
