Electronics wizard Lawrence Casserley is something of a phantom, a ghost musician, a mute who can only speak through the voices of others. He has no sound of his own, but, like a parasite feeding on its host, uses the analogue input from the clarinet of Noel Taylor and the contrabass of Guillaume Viltard to function as triggers for his electronic re-shaping. Their sounds become bounced back to them mangled, distorted, re-imagined: producing weirdly spectral reflections of their playing. It is a musical circuit diagram, a feedback loop of potentially infinite regression. It presents to them conflicting impulses, in which the immediate past struggles with the immediacy of the present. The process creates a music of shifting hierarchies in which puppet and puppet master constantly swap places, but which can nevertheless discover a formal and crystalline coherence.
