This work was created using short wave radio signals, field recordings, dusty analog devices, as well as samples from Three Quarter Tone Piano Pieces by the American modernist composer Charles Ives (1874-1954) as central sound source.

The work of Claudio Rocchetti is a deep plunge into thick sound, investigating its innermost workings. Using a variety of devices such as turntables, audio cassettes, samplers, radios, and microphones, often incorporating other objects and traditional instruments, Berlin-based Rocchetti builds compelling structures that employ sound as sheer matter, mass, and impact. "I have a very direct approach to sound, trying to act on instruments and devices," he says.
