Although the creation of sound experiences is transient, the ensemble goes beyond performance alone by compiling a body of work – a mark in the flow of time, the formation of a repertoire.

premieres by SoloVoices.

Founded in 2008, the SoloVoices ensemble is dedicated to performing new and contemporary music. The four-voice quartet, two female and two male singers, intentionally seeks a wide variety of repertoire ranging from the 1960s to the present day, including world premieres. SoloVoices often works directly with composers, exposing itself to unknown musical territory – negotiating through uncertainty. New musical languages must be understood and the works must not only be sung but performed.

Since 2015, SoloVoices has devoted itself in part to works for voices and electronics.

Following in the footsteps of Electric Phoenix, which has been mixing classical and electronic music since the late 1970s, the ensemble is working on a new sound aesthetic. It is committed to music that is freer in style and more diverse in form. In order to perform electronic pieces from the late 20th century, the quartet collaborates with the ICST - Institute for Computer Music and Sound Technology - in Zurich. Together, they are dedicated to exploring a variety of electronically produced sounds where the original devices have become obsolete due to technical developments.

In 2016, SoloVoices performed Stockhausen's ‘Stimmung’, a musical monument that turned not only the classical repertoire on its head but also, in a broader sense, the soundscape of the 20th century. The ensemble had the opportunity to work with the original performers of ‘Stimmung’ and the Stockhausen Foundation for Music, which subsequently presented them as Stockhausen's new heirs.

SoloVoices explores cutting edge repertoire. The ensemble feels its way forward, stumbling, experimenting without any guarantees - ultimately creating a musical universe in which every sound becomes tangible. A sometimes intoxicating, sometimes unsettling soundscape nevertheless envelops and sustains the listener with its airy texture.

‘Extrêmement oisif, extrêmement libre, et par nature et par art’ (Extremely independent, extremely free, both by nature and by art), Jean-Christophe Groffe has found in music a way of life in keeping with this temperament. Jean-Christophe Groffe is recognised as a highly skilled and versatile artist, equally at home in the early (Renaissance) and contemporary repertoire. He is also known for his research work (in particular in collaboration with the Institute for Computer Music and Sound Technology-ZHdK) and his work as a moderator and curator of independent projects. Founder and artistic director of Thélème, an ensemble dedicated to an open and original interpretation of Renaissance music, he is also a member and co-director with Francisca Näf of SoloVoices, which explores contemporary and experimental music. Jean-Christophe Groffe has participated in numerous recordings and is regularly invited to take part in radio programmes. The album ‘Baisiez moi’ (thélème/Aparté) was honoured in 2022 with a prestigious Gramophone Classical Music Award (Early Music). In 2024, as a director, Jean-Christophe Groffe created a music video with the participation of Sting (also featured as a singer on the Thélème album All we get is life), thus continuing his desire to cross the boundaries of musical genres.
