Lossz is the project of UK-born, Berlin-based composer, instrumentalist and sound artist Hayden Prosser. 

His background in avant jazz led to him leading the acclaimed group Tether, and brought him to the forefront of the contemporary improvised music scene. Under the Lossz moniker, Prosser gradually brought explorations in electroacoustic composition and improvisation to the fore of his sound.

Focusing on auditory perception, listening experience and the intricate intersections of acoustic and electronic worlds, Lossz often combines double bass with found objects, field recordings and digital instruments to create a pensive and mercurial collage of sound.

At Loop, Lossz is teaming up with Spherical Aberration for an interactive audiovisual installation.
