Sonja Indin
Sonja Inderbitzin was born in Zurich in the Swiss canton of Zurich in 1980. She studied jazz singing with the Swedish jazz singer Marianne Racine at the Zurich University of the Arts (ZHdK), with the Swiss jazz singer Lisette Spinnler in Basel and with the British jazz singer Nia Lynn (A Flexible Harmonica, The Bannau Trio) at the Royal Welsh College of Music & Drama in Cardiff, Wales. She studied at the ZHdK from 2005 to 2010 and obtained a Master of Arts in Education.

Sonja Indin has been performing with her own band since 2005. The names as well as the line-up of the band have changed several times. In winter 2010/2011, Sonja Indin's debut album (vocals, piano, composition) was recorded with Simon Kessler (guitar), Fridolin Blumer (double bass) and Markus Neuweiler (drums). They were joined by four guest musicians Thierry Kuster (saxophone), Sebastian Müller (vibraphone), Ambrosius Huber (cello) and Andreas Ambühl (bass clarinet), who have already played in previous bands. Their debut album "Do you know me?" was released in 2011 via Brambus Records.

On 16 December 2014, a successful crowdfunding campaign started on 100-days.net to finance the Tucholsky chanson CD "Augen in der Grossstadt". The CD with chansons on texts by the German writer Kurt Tucholsky (1890-1935) was released on 13 February 2015. Sonja Indin and the classical pianist Isora Castilla have reinterpreted songs from the 1920s for it. The CD for the stage programme of the same name with the actress Beren Tuna had already been recorded at the start of the crowdfunding campaign; the campaign was intended to support the recording production.

From 2007 to August 2013, Sonja Indin also worked as a singing teacher in Dübendorf. From 2011, she also worked as a singing teacher at the Musikschule Konservatorium Zürich (MKZ).
