The Duo comprises Rhodri Davies, an eclectic harpist who has performed with groups such as the Cinematic Orchestra and The Magic Numbers, and his musical collaborator, saxophonist John Butcher, who is also, interestingly, a Surrey Physics graduate.

In this concert, the DUO will turn the conventional use of instruments on its head and explore the full range of sound and performance possibilities through the use of amplification, extended techniques and imagination; often to the point where it is no longer clear where the sound is coming from.

Butcher and Davies began working together in 1997 and made their first live album together in 2000. Ten years later they produced Carliol, on which sounds this concert will expand. This relationship aids the improvisational nature of their collaboration, bringing out conversations and connections in the music. Both have worked in multiple collaborations with improvisation legends such as Derek Bailey and Evan Parker, always pushing the limits of their instruments to create interesting and engaging music.
