Vas Deferens Organization is an American experimental band and a production team founded in Dallas in 1994 by Matt Castille in association with Christopher Moock, Jason Cohen, Barbara Cohen, Craig Carlton, Breck Outland, and Reagen Boone. In 1995 Eric Lumbleau joined the group. From 1995 through 2007, VDO was a loose collective centered around Castille and Lumbleau and ever-changing collaborators. Christopher Moock reunited with Castille and Lumbleau in 2007.
They have worked, among many others, with Brad Laner of Medicine fame, Mercury Rev, and Ariel Pink with whom are friends. Pink is also a long-term fan of Mutant Sounds, a blog devoted to esoteric music from various eras and corners of the world, run by Eric Lumbleau and Matt Castille.
Their musical output is extremely diverse, ranging from minimalism, musique concrete, audio montage, raga and ethnic music to krautrock.
Some of their most notable productions include Cruising in the Neon Glories of the New American Night (1996) by Mazinga Phaser (produced by Castille), and Ariel Pink With Added Pizzazz (produced as Vas Deferens Organization). One of the tracks from the latter album appeared in an alternative cut on Ariel Pink's Haunted Graffiti 2010 record Before Today.
Among their collaborations, the most noteworthy ones would be Transcontinental Conspiracy recorded with Brad Laner with the addition of Jason Russo, Suzanne Thorpe, and Sean "Grasshoper" Mackowiak from Mercury Rev. It was self-released in 1996 on Quaquaversal Vinyl and re-issued in 2011 on Niklas Records with a previously unreleased track, Scheming Foils, that also featured Laner.
Eric Lumbleau, Matt Castille and Christopher Moock have also released their own solo recordings, under monikers of Sound, Muz and Christopher Moock respectively.
While not achieved any sort of commercial success, the band has achieved a critical success.
