Robert Worby presents more performances from this year's Cut & Splice Festival, co-curated by Hear And Now and Sound And Music at the ICA in London last week. This year's theme is Collectives, and features performances by Jennifer Walshe's Grupat collective, and the Wandelweiser collective. Grupat has a playful and wide-ranging approach that encompasses film, sonic sculpture and interventions alongside concert music. Wandelweiser music is about "the evaluation and integration of silence rather than an ongoing carpet of never-ending sounds", inspired by the ideas of John Cage.
And in the Hear And Now 50 series, composer and rock musician Tyondai Braxton explains why he is so inspired by the Poème électronique by Edgard Varèse, while Gillian Moore tells the story of Varèse's long struggle to create a futuristic music that he finally achieved in this work, composed for an array of hundreds of loudspeakers at the 1958 Brussels World Fair.
