Violinist, painter and sculptor, he was born in 1958 in Biel/Bienne in the Jura region of Switzerland. He started studying violin as a child and never stopped since then. Soon improvisation became very important, and he spent many hours playing with his brother, Peter. In his thirties, he spends a year in Milan, developing research on musical languages and pursuing his interests in sculpture and painting. It has been written that Boss plays the violin, realizing a wide range of sounds, intervals and nuances with a remarkable sense of space and composition. He has worked as a stage technician for many years in the city theater of Biel/Bienne and Solothurn (TOBS). Later, he worked with refugees in the Jura Mountains, to support the work of local farmers and foresters. The stories of the people coming from all over the world and the time spent with them strongly influenced Matthias Boss’s art. He has made numerous recordings and performed concert tours in Switzerland, Italy, Portugal, Austria, Hungary, Germany and England. During this tours, he has been involved in several collaborations with some representative artists on the international improvisers scene: Carlos Zingaro, Roberto Del Piano, Benedict Taylor, Tom Jackson, Marcello Magliocchi, Abdul Moimeme, Paulo Curado, Martin Walter, Bruno Gussoni, Paulo Chagas, Joao Pedro Viegas, Jean Michel Van Schouwburg, Jean Demey, Maresuke Okamoto, Nicola Guazzaloca, Marcio Mattos, Sue Lynch, Guy-Frank Pellerin, Eugenio Sanna, Jonas Kocher, Adrian Northover, Daniel Thompson, 876 Trio, and many others. All these collaborations were and still are very enriching for Matthias Boss.
