Tezgah (meaning loom in English; Webstuhl in German) is a live performance built around a 40-year-old loom that once belonged to lifelong weaving master Hatice from Ortahisar, Turkey. Built by her grandfather, this loom is today partially broken, heavily worn, and carries an unfinished hand-woven kilim rug. It is the instrument on which Saba Arat learned how to weave and produced many of her works. Rather than completing the textile, the loom has been transformed into a playable instrument by Saba Arat and Karlo Sono, with immersive sounds by Tarxun. Saba continues to weave into the kilim during each performance.

The half-woven kilim stretched on the loom contains seven conductive touch points and multiple microphones. Saba weaves, touches, strikes, and activates the textile in real time, while Karlo Sono and Tarxun live-mix and process the resulting signals and sound material. The performance moves through different modes and phases, merging into a raw, hybrid sonic state the trio refer to as loom-metal.
