Sin Cos Tan is a collaboration between Juho Paalosmaa and Jori Hulkkonen, who have worked together previously, namely on Juho's other band, Villa Nah's debut album Origin, which Jori produced, and in return Juho made a guest appearance on Jori's album Man From Earth of the same year. Sin Cos Tan debuted their live set at 2012 Flow Festival in Helsinki, and have since picked up a host of online support, ranging from Noisey. Sin Cos Tan are designed exclusively for a digital interface; that’s not to mention trigonomic functions on a graphing calculator, but rather the Finnish synthpop duo consisting of Jori Hulkkonen and Juho Paalosmaa, who are well-suited to these MIDI-val times of artificially-inseminated sound. Having been raised on music of such an idiom – i.e. eighties new wave full of affected beats and racks of synthesizer keyboards – Sin Cos Tan estimate that it’s only a matter of time before crossfades and software effects are regarded with the same integrity as any given shredding guitar solo. And their music is their virtual guarantee. Emphasis on the virtual. As they boot up their CPUs for their upcoming Ja Ja Ja performance (29 November at London’s The Lexington), we catch up with Sin Cos Tan to find out what operating system they run on.
