Quatuor Bozzini

Compositions for string quartet by James Tenney, Horaţiu Rădulescu and Éliane Radigue lead us into the world of micro-tonality. Vibrating wave forms open up astonishing fields of perception.

Past Dates

The Canadian Quatuor Bozzini lead this concert into three different yet related energy fields emanating from the world of microtonality. James Tenney’s (1934 – 2006) string quartet “Koan” releases perceptual marvels by gliding through a simple, linear process of progressively higher microtonal intervals. “Before the Universe Was Born”, the fifth string quartet by Horaţiu Rădulescu (1942 – 2008), explicitly takes up this year’s festival focus on the beginning of time. It is a shining example of Rădulescu’s radical compositional approach. The evening eventually flows into “Occam Delta XV” – a recent addition to Éliane Radigue’s (*1932) cycle of purely instrumental works, created for and with the Bozzinis. Its large spectrum of vibrating undulations is inspired by a mythical ocean found in David Duncan’s (1913 – 1999) science-fiction novel, “Occam’s Razor”, as well as by William of Ockham’s (ca. 1288 – 1347) influential methodological principle expressed most succinctly in his own words, “The simplest, the best.”
