Sonja was born in the Swiss Mountains in autumn 78. At the age of four, she got in touch
with her 1st instrument: the piano. Aside her classical music studies, she was on the
search for other musical styles. As a Depeche Mode and David Bowie young teenage fan,
she was a bit out of her time. With the wonderful discovery of acid music sounds and
electro rythmics she did while visiting underground and open-air parties all over
Switzerland and Germany, she dived into the whirl of electronic music.
In the mid-
nineteens, when the rave Syndroma turned into a tasteless carnival, she devoted herself
to weird parties organizations in several Geneva’s squatts during 3 years alongside the
Mentalgroove crew. At this time she gave up her piano studies for a new bought Roland
R8, started to get professional bookings (Weetamix, Usine…) and to search for silence.
She began the new century teaming up with amazing friends. Miss Kittin opened her the
doors, while Weetamix gave her a residency alongside Luciano. After several
collaborations with artist- friends (Serafin, Dandy Jack…) and crews (MUTEK Chile, Soap
System Istanbul, Cosmic Chile Zürich), Sonja starts a new LIVE/DJ project named
Junction SM in 2004 alongside Dandy Jack. It consists on an impressive combination of
live and dj sessions that lasts for hours. She also did several solo-live sets. Devoted to
her studio, she continues to manipulate sounds and silences…
Since 2005, the
label/collective Ruta5 has been under reconstruction and a bunch of label parties are
regularly organized. The productive side has not been forgotten, with several releases:
among others, Sonja on Karat’s compilation, Katapult various 3, that appeared at the end
of 2007 on CD and on two split vinyls.and Junction SM on Kalk Pets and Lessizmore in
Today, Sonja is also working as a sound designer for the swiss-french TV TSR.
After some more remixes (Fine Art recordings, Monika enterprise, Kalk Pets), she is
preparing some fresh food for her turntables.
