Formed in 2005 by American-born musician James Ginzburg and British contemporary art curator Paul Purgas after meeting through the consistently fruitful Bristol, U.K. music scene, the pair found that, while their day-to-day backgrounds differed, their musical reference points seemed to match. Emptyset's debut release, the Acuphase EP, came in 2007, followed later that year by the Isokon EP. These early 12"s drew heavily on minimal techno, and it wasn't until the release of Emptyset's self-titled 2009 debut album that the duo's original concept came into fruition. The album explored the sound of reprocessed sine waves through various compressors, EQs, and amplifiers, feeding back on themselves and creating a throbbing, bass-heavy sound that drew as much from the Bristol bass music scene as it did from techno.
Two years later, in 2011, Emptyset released their second album, Demiurge. Refining their sound even more, the album pushed the duo deeper into experimental territory, while capturing the ear of German techno legend Chris Liebing. Eager to collaborate, Liebing released the duo's single Altogether Lost on his own CLR label. Featuring vocals by Underground Resistance member Cornelius Harris, the single took Emptyset's sound to a wider audience. A second release for CLR, the Avichi EP, came a few months later.
A visit to the eerie, unfinished Victorian gothic Woodchester Mansion in Gloucestershire, U.K., while on a break from recording their second album captured the duo's imagination. Keen to exploit the building's unusual spaces, Emptyset returned there to record their third album. Setting up a basic studio in the middle of the house, they enlisted the help of sound engineer Matt Sampson to mike up various rooms, which would in turn record the sound of their processed signals, utilizing the building's structure to inform the final sound. The skeletal compositions were then reworked back in the studio, with the result being 2012's Medium. The duo rounded out 2012 with the release of the Collapsed EP on experimental electronic label Raster-Noton and a live sound experiment at the University of Westminster's Ambika P3, a 14,000 square-foot, triple-height performance space. ~ Richard Wilson, Rovi
