Material Frequencies is a live audio-visual performance by jewellery artist Gina Melosi and multimedia artist Ossagrosse, featuring cello recordings by Gianna McDonald.

The work explores the shared language between sound, touch, and transformation. Jewellery-making tools, tape loops, and recorded cello fragments become material for live improvisation, where friction, polishing, and degradation are treated as acts of care as much as erasure.
