<p>When the musique concrete pioneer John Cage first experienced the effects of an anechoic chamber at Harvard University in 1951, he heard just one thing; his heartbeat and the blood flowing through his body. Met with true ‘silence’ he left the chamber enlightened, realising that finding true silence is impossible. </p> <p>Cage went on to transform this ‘silent’ experience into ‘4’33” , but the performance-artist Dani Ploeger adopted a different approach to making his insides audible in 2011’s with ELECTRODE. Inserting a sensor-connected electrode into his anus, Ploeger tightened and relaxed his sphincter muscles to match the contraction data of a male orgasm. The sound which emanated from Ploeger’s anal cavity gurgles with heavily distorted drone and subterranean frequencies. </p> <ul> <li>Jack Needham</li> </ul>
