Silence as a form of expression is the common denominator this evening. The American sonic artist, John Colley breathes life into supposedly inanimate equipment and materials, moulding an acoustic microcosm that succeeds in making the inaudible audible. As J.M. Coetzee wrote in his novel, “The Life and Times of Michael K”: “We sleep too soundly to notice the scraping of an ant’s foot.” Another kind of silence is demonstrated by the Norwegian improvisation quartet, Supersilent. Here – with the aim of attaining the most democratic means of playing together – silence is used as a means of communication, as a musicians’ round of Q & A. Perhaps that’s the reason why the band, to its chagrin, constantly gets put in the box marked “Jazz”. Biosphere, also from Norway, has you anticipating silence even before it happens. Contemplating nature and introspective retreat inspire his infinite, slowly meandering tonal tales that induce in the listener a state of timelessness of almost religious dimensions.
