Emptyset Biography (Wikipedia)
Emptyset is a Bristol-based production project, formed in 2005 by James Ginzburg and Paul Purgas, who say that by working across performance, installation and the moving image they are examining the physical properties of sound, the legacy of analogue media reflecting upon structural/materialist art production and the perceptual boundaries between noise and music. Emptyset has produced installations for Tate Britain and the Architecture Foundation in London, and presented live performances at Arnolfini, Spike Island Artspace, Kunsthalle Zurich, Sonic Acts XIV and Club transmediale (CTM) festival.
Writing in the magazine Fact, Josh Hall stated that the duo are preoccupied with interstitial spaces: the points at which distortion takes on its own volition; at which form begins to dictate content; at which techno yields to the equipment with which it is made.
Ginzburg and Purgas began Emptyset in 2005 to explore their shared interests in rhythmic music and bass. Both have backgrounds within Bristol's club music scene: Ginzburg runs Multiverse, a studio complex and collective of record labels that initiated (among others) Pinch's Tectonic and Subtext, which has released much of Emptyset's earlier releases. He also produces club tracks as 'Ginz'. Purgas, who now lives in London, has a history in art and sound art curation, a background in techno, and curates exploratory electronic music events under the banner 'We Can Elude Control'.
