Šalter Ensemble operates on the border between free improvisation and composition, focusing on collective processes as a central part of its practice. The project is an international electro-acoustic ensemble initiated in 2017 by Jonas Kocher in collaboration with Zavod Sploh Ljubljana and Izlog Festival Zagreb, and has since performed at numerous venues and festivals in Slovenia, Croatia, Italy, Switzerland and Serbia.

The ensemble consists of outstanding personalities from the Swiss music scene, the Slovenian music scene and, in the 2023 edition, exposed representatives of the Styrian music scene. The musicians come from a wide range of backgrounds – from jazz to traditional and folk music to contemporary improvised and electronic music – and are from different generations.
