|Members||Svein Egil Hatlevik|
Hatlevik started using the Zweizz alias in 2003 after leaving the Norwegian black metal group Dødheimsgard. According to Hatlevik, Zweizz should be considered a one man band, not a solo project. Hatlevik defines the musical style of Zweizz as a mixture of IDM, noise, electroacoustic music and black metal.
The first Zweizz release was the 7" EP Black Necrotic Obfuscation, issued through Vendlus Records in 2004. On March 24, 2007 Zweizz released his debut album The Yawn of the New Age, also through Vendlus Records. Later the same year Epicene Sound Systems released an untitled Zweizz cassette EP in a limited quantity of 30 copies. Side B of this release is built entirely from recordings of the Soviet ANS synthesizer.
In 2011, the Norwegian record company Jester Records released the album Zweizz & Joey Hopkins that Hatlevik had been making with the late US composer and musician Joey Hopkins before the death of the latter in 2008.
