Sollmann studied Electroacoustic Music (ELAK) at the University of Music and Performing Arts in Vienna. Besides his current involvement in club culture, he explores the tension between mechanical sound production, sound installations and electroacoustic compositions in various projects. Sollmann currently works with Konrad Sprenger on the development of the Modular Organ System, a spatial sound concept based on air-powered organ pipes, controlled via MIDI.
Sollmann and John Gürtler released the album Gegen die Zeit on the Sky Walking label. Now, he’s composing for the Berlin Zafraan Ensemble, making crossovers between new music, improvisation and ambient. Sollmann's conceptual composition “Monophonie”, which he wrote for instruments built by composer Harry Partch, sound sculptures made by Harry Bertoia, and for one of Hermann von Helmholtzs’ sirens, was premiered at the Berliner Volksbühne in collaboration with the Ensemble Musikfabrik in 2017. It was also performed at Kampnagel in Hamburg, and at the Ruhrtriennale in Bochum. A new record release is planned for 2020.
