Ewa Justka is a polish electronic noise artist and instruments builder based in London.

Justka’s main field of research is based on exploration of materiality of objects, vibrant, ontological systems (human bodies, plants’ bodies, electronic circuits: varied range of micro and macro environments and relations between them) and an investigation of modes of quasi-direct perception through noise performance actions, interactive installation, DIY electronics, hardware hacking, plant-molesting, breaking, deconstructing and collaborating. In her artistic work Ewa attempts to explore the concept of materiality of the hidden.

Ewa has performed at Network Music Festival, Birmingham, UK; Supernormal Festival Oxfordshire, UK, Club Transmediale Festival Hacklab, Berlin; Exploding Cinema, Goldsmiths College, London, UK; STEIM, Amsterdam, NL; Moving Forest, Chelsea College, London, UK; Colour out of Space, Brighton, UK; Beam Festival, Brunel University, London, UK; Cafe Oto, London, UK and more.
