The Estonian Helena Tulve, for example, practices acoustic alchemy with influences from French spectralism, Gregorian chant and Eastern music. Her work Lijnen, on texts by the Flemish poet Roland Jooris, wholesales in iridescent timbre mixtures.

Further this afternoon the labyrinthine ‘classic’ Licks & Brains II (1988) by the Dutch Swede Klas Torstensson. There is a world premiere by composer Wilbert Bulsink, who in his yet-to-be-written work wants to invite the audience to adopt contrasting listening positions: “I like compositions in which I have to keep readjusting my ears to be able to follow what I am listening to.”
