Since its first foreign tour in 1992, the Sine Nomine has received regular invitations to perform in the United States and Canada with concerts in Los Angeles, San Francisco, Vancouver, Montreal, Cleveland, Washington DC, Boston and New York. The group’s performances in such prestigious concert halls as Carnegie Hall, New York, Wigmore Hall, London, and the Concertgebouw in Amsterdam, as well as the Louvre and Orsay Museums in Paris received considerable acclaim. The Quartet has also participated in some of the major European music festivals, namely Lucerne, Montpellier (Radio France), Schleswig-Holstein as well as the Lockenhaus Chamber Music Festival and the Schubertiade in Schwarzenberg, Austria.

Parallel to its classical works, the Quartet has not hesitated to perform contemporary music and to widen its range by collaborating with jazz musicians. As it continues to pursue its career and development, the Sine Nomine Quartett hopes to share its passion with a wider and more diverse public. With this goal in view, the Quartet founded in 2001 the Sine Nomine Festival which takes place every two years in Lausanne.

Founded in Lausanne, Switzerland, the Sine Nomine Quartett was awarded first price in the Evian International Festival in 1985 as well as the Press Jury Price. In 1987, the Sine Nomine were price winners in the first Borciani Competition in Reggio Emilia, Italy

Influence and inspiration
Of the many friends and supporters of the Sine Nomine Quartet, it was their early mentor, the late Rose Dumur Hemmerling, who shared with them her passion and feelings for the great string quartet tradition. Other sources of inspiration came from the Melos Quartet, the pianist Jean Hubeau and the cellist Paul Tortelier ; Sofia Gubaidulina, and Henri Dutilleux, who chose the Sine Nomine Quartet for recording by Erato of his work Ainsi la Nuit. Performing with other musicians has enabled the Sine Nomine to share its passion for chamber music. Among those with whom the group has enjoyed a close relationship are Michel Dalberto, Bruno Canino, Philippe Bianconi, Marie-Joseph Jude, Pierre-Laurent Aimard, Paul Lewis, Michel Portal, Pascal Moragues, Paul Meyer, Martin Fröst, Maurice Bourgue, Emmanuelle Bertrand, François Guye and Rafael Oleg. Close ties have also been formed with other quartets such as the Vogler Quartet in Berlin and the Carmina Quartet in Zürich.

Repertory
The Sine Nomine's wide repertoire ranges from Haydn to Kurtág, including the great romantic and classical works. The group has also performed such rare pieces as Enesco’s Octet and the concertos for quartet and orchestra by Schönberg, Martinu and Schulhoff. They have also premiered several contemporary works, most of which were composed especially for them by Balissat, Blank, Hosokawa, Hostettler, Wustin, and Zinsstag, among others.

Finally
As well as playing in the Sine Nomine Quartet, the four musicians teach at the Lausanne and Geneva Music High Schools. A primary objective in their contacts with students of chamber music is to pass on the need to define one’s own identity while gaming the respect of others.
The Sine Nomine receives financial aid from the City of Lausanne and the State of Vaud. In addition, the Association of Supporters of the Sine Nomine Quartet, founded in 1994, helps finance its activities, particularly overseas.
