The Berlin-based Reidemeister Move pushs the possibilities of long tones in natural harmonies for low instruments. Robin Hayward‘s self-designed microtonal tuba and contrabassist Christopher Williams‘ slow bows meld in an unearthly fusion of overtones, undertones, noise, bodily rhythms, and spatial resonance. The members’ work with Berlin’s echtzeitmusik scene and LaMonte Young’s legendary Theatre of Eternal Music grounds RM’s precise and immersive sound. Formed in 2011, the duo can be heard on Corvo Records and Recital Recordings, as well as venues across Europe and North America. Their name is an homage to the mathematical theory of knots.
