The sound of Ewa Justka’s noisy music is created with her own inventions, including homemade synths, hacked hardware and electrified plants. The London-based Polish artist is attempting to explore the materiality of the hidden, working with multi-sensory presentations of analogue signals, combining sound and its visual representation. She’s also known for her works with Jayson Haebich and Manni Dee, and recently released “Acid Smut” on Graham Dunning’s label Fractal Meat.
