‘Favourite Animals’ (Sloth Racket extended lineup, 2017)

‘Lurching between riff and abstraction…maintains an elegant balance between emergent melody and the wilder activity at its fringes’ 
– The Wire

‘Startling moments of altered perspective’ 
– Bandcamp Daily

‘Gritty and anarchic…Favourite Animals confirms Roberts’ talent as a composer and Luminous as a label to watch’ 
– Jazzwise


‘See The Looks On The Faces: Live Recordings’ (2017)

‘The group’s ability to move freely from jointly articulated statements to darkly atmospheric extended techniques is remarkable and this tape gives a fascinating glimpse of where they might go next.’
– The Wire


‘Shapeshifters’ (2017)

‘The UK quintet tend not to stay put.’
– The Wire

‘Superb ensemble and individual playing’
– Jazzwise

‘This is meaty, powerful music, thoughtful and multi-dimensional with no lacunae and no navel-gazing.’
Dalston Sound


‘Triptych’ (2016)

‘Consider this an important contribution to the debate about spontaneity versus form.’
– Jazzwise

‘An agreeably spicy goulash of free improvisation, grumpy riffs and bluesy themes.’
The Quietus

‘Nobody in their right mind is going to call this row slothful.’
Record Collector

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 doing four UK tours to date. Sloth Racket’s third studio album A Glorious Monster is out on the Luminous label.
