a bonus full-length disc titled Interregnums, featuring songs that were more ambient and contemplative than usual Prefuse 73 material. Along with partners Peter Rentz, Carolina Chaves, Ben Loiz, Carlos Niño, and Paz Ochs, Herren started the Eastern Developments Music label. In June 2008, Herren announced the formation of a new collaborative project, Risil, which includes members of Sunn O))), Hella, School of Seven Bells, Pivot, and others. On June 24, 2009, the supergroup released their debut LP, entitled Non Meters Volume 1. Herren also released a new Savath & Savalas album, entitled La Llama, earlier in March of the same year, and a new Prefuse 73 LP entitled Everything She Touched Turned Ampexian. In 2009, under the name Diamond Watch Wrists, he and Zach Hill contributed a cover of a Pivot song to the Warp20 (Recreated) compilation. The group later released the album Ice Capped At Both Ends. Herren released three sets under the name Prefuse 73 in 2015: two EPs (Forsyth Gardens and Every Color of Darkness) and an album, Rivington Não Rio.
