Emerging young composers are creating new works for the 4tet Laboratoire. The composers come from a wide variety of backgrounds; Simon Bahr, for example, explores sound discoveries found on the internet. Aya Metwalli combines the tradition of Arabic music with contemporary music and her experience in literature, theater, and dance. Juliana Santacruz is influenced by South American music, which gives her a broader perspective on new classical music in Europe. Christian Spitzenstaetter often combines the worlds of jazz and classical music in his works, and is also active as a conductor and artistic director of operas and interdisciplinary projects. All four composers are also active on stage as performers. These collaborations were deliberately chosen to blend the roles of composer and musician and allow both parties to inspire one another.
