In a special commission, Biosphere + The Pitch premiered at CTM 2014, highlighting an old GDR synthesiser, the Subharchord. Presented at the Funkhaus Nalepastraße, home of the GDR National Broadcasting Service until 1990, the piece was performed as part of the wider programme titled “The Child of the Golden Age" which told the Subharchord’s story, from its invention and discovery to the present day, intermingling electronic music, cold-war politics, and the experimental music scene in Norway along the way. The afternoon also included an exclusive preview and discussion of the "Subharchord – A Child of the Golden Age" documentary directed by Ina Pillat, who recorded the CTM performances to incorporate into her film.

Built in the 1960s in East Berlin, the Subharchord was an electronic sound generator ahead of its time, of which only 7 instruments were ever built. Based on the Mixturtrautonium, an instrument developed in the West by Oskar Sala, the Subharchord differs from conventional synthesizers in that it produces subharmonic sounds, or "undertones" of a given note, which, unlike the more familiar "overtones", do not exist in nature. As nobody but Salas had mastered or played the Mixturtrautonium before his death, it seemed that the sound world of subharmonics was lost… until the Subharchord resurfaced.

Biosphere (Geir Jenssen) from Tromsø, Norway, has been making electronic music since the mid 80s, and is renowned for the style known as “arctic ambient”. The first Biosphere releases appeared in 1991 and he is on the roster of labels such as of Eno’s All Saints Records and UK imprint, Touch.

Exploring the tension between tone, pitch, duration, and interaction, The Pitch use bass patterned structures in prescribed combinations to create “liquid music”. The group was formed in 2009 by Michael Thieke (clarinet), Koen Nutters (acoustic bass), Morten Olsen of MoHa! (vibraphone/percussion), and Boris Baltschun (electric pump organ / function generator). A Pitch performance in Brussels was released as an LP, Transposition Zero, on French imprint Gaffer Records in 2010.
