Jost Muxfeldt is a German/American artist, composer, philosopher, and programmer, whose work often focuses on trans-media and phenomenology, exploring the rational and irrational channels between artistic and conceptual disciplines, and pursuing their self-transfiguring implications.

In 1991 he moved to Berlin, where he began working as an artist and composer, independently as well as with other artists such as Arnold Dreyblatt, Martin Riches, Laura Kikauka, and Stephan Wunderlich. He also began working in architecture for Daniel Libeskind, Arata Isozaki Architects, Schultes Frank Architekten, and later with many other prominent Berlin architects.

The first performances of his music and sound works were organized in Darmstadt and in Munich by Stephan Wunderlich in 1998/1999. He has published and lectured in philosophy, in part on the work of Arakawa and Madeline Gins. His audiovisual work, Audio Kinematics, has been shown in numerous  venues through Europe, including  the Tesla Media Art Center at both the Ultraschall and Transmediale Festivals, in the Centre D'Art Santa Mònica for the Sónar Festival in Barcelona, at the Via Festival in Maubeuge, and at the Exit Festival in Paris-Créteile. Continuing developments of initial ideas for Audio Kinematics have led him to further philosophical and artistic inquiries into the question of "What is space? ".
