Cath Roberts (they/them) is an improviser, composer and artist based in London, whose work combines acoustic and electronic improvised music, experimental composition, and DIY publishing practices.

On saxophones Cath has collaborated with a wide range of artists and ensembles internationally for over a decade. Their band Sloth Racket has released five studio albums, touring widely and ‘lurching between riff and abstraction’ (The Wire) since forming in 2015. Other recent exploits include playing with Chris Corsano as part of his 2022 Cafe Oto residency, and being one of two UK artists (with Mandhira De Saram) commissioned by Australian Art Orchestra to co-create and perform Fresh Water – Salt Water in Melbourne and Huddersfield (a hcmf// and AAO co-commission, also in 2022).

Cath works with live electronics (SOMA Lyra-8 synthesiser, samplers, and small tabletop machines) in ongoing collaborations with Kate Carr (as Quartz Sand), Graham Dunning (as Grid & Robots) and Tullis Rennie. Be unafraid to open things up, a solo improvisation on tabletop electronics, was released on Fractal Meat Cuts in 2022, and Cath’s sampler-based solo collage set Patch Dynamics had its first outing at hcmf// in 2024.

In 2021 Cath was commissioned by hcmf// to create And then the next thing you know, a cross-artform installation/performance piece involving a giant, hanging, fragmented graphic score, elements of which are being integrated into a new audio-visual collaboration with Tullis Rennie. In 2024 Cath established the DIY small press Ink-Paper-Sound, and they co-run the Luminous label and the BRÅK concert series.
