Improvisational vocalist Saadet Türköz was born in Istanbul to parents who were Kazakh refugees from East Turkestan. She learned the rich oral and musical traditions of Central Asia from the elderly people of the Kazakh community in Istanbul. Their tales of their homeland and long journeys to Turkey later became an imaginative source for her improvisational singing. Another source has been the Koran she listened to as a child.

At the age of 20, she moved to Zürich, where she experienced the new worlds of free jazz and improvisation. These encounters prompted her to take an experimental and unbiased approach to her musical roots. She has performed solo and with other musicians at home and abroad, releasing her first album in 1994. Her collaborations include work with Okkyung Lee, William Parker, Carl Stone and Bobby McFerrin.

Swiss guitarist Beat Keller works in avant garde jazz, experimental and improvised music, aiming to develop a distinct musical language through the exploration of extended playing techniques, guitar tunings and feedback, as well as acoustic guitar.
