Sloth Racket is a band of UK improvisers led by baritone saxophonist Cath Roberts, with Sam Andreae on alto saxophone, Anton Hunter on guitar, Seth Bennett on bass and Johnny Hunter on drums. They play Cath’s compositions, combining written fragments with graphic notation to explore the balance between freedom and structure. The results are always different, and so far have ranged across musical territories taking in fiery free jazz, minimal improv textures and heavy riffs.

The band formed in 2015 when Jazz North East invited Cath to present a new project at Gateshead International Jazz Festival. Everyone agreed this had to be more than just a one-off, and they went on to appear at London Jazz Festival, Brighton Alternative Jazz Festival and LUME Festival, as well as touring every year. Sloth Racket have released three studio albums on the Luminous Label and one live album on Tombed Visions.
