Beresford played in Derek Bailey's Company events and in the groups Alterations with David Toop, Terry Day and Peter Cusack, and the Three Pullovers with Nigel Coombes and Roger Smith.

Beresford has continued to play free improvisation with a number of prominent musicians, including Evan Parker, Lol Coxhill, John Zorn, and Han Bennink.

He has also worked with a number of popular musicians, including Ray Davis, The Slits, Frank Chickens, Ted Milton and The Flying Lizards.

British songwriter and performer Katy Carr cites Steve Beresford's lectures on musical themes associated with Free improvisation, Experimental music, John Cage, musique concrète, Diamanda Galás and The Slits as a source of initial inspiration with regards to the creation of her debut album, Screwing Lies released in 2001.

The authors of the Penguin Guide to Jazz Recordings called Beresford "one of the unsung geniuses of modern European music, a constant presence whose contribution is usually unremarked.
