Together with Sonja Oberkofler (Saxophone), Márk Seres forms the Somnium Duo, focusing on contemporary music repertoire for electric guitar and saxophone. They collaborate with various composers to expand and build the repertoire for these instruments.

In this duo with Angelo Beltrame (Cello, Electronics), Márk Seres engages in a more experimental approach, combining improvisation and composition. They work with electric guitar, cello, electronics, analog synthesizers, computer-based sound, and visuals.
