Saunders’s assigned #15 is part of a series that draws material from his modular composition project #[unassigned]. A bespoke series – to use his word – and this realisation was tailored for a specific occasion, at St Paul’s Hall, Huddersfield in April 2015, and for a particular incarnation of Apartment House. Saunders himself, working with dictaphones and shortwave radio, and Kerry Yong playing chamber organ create a fuzzy glow, bristling with sferics, that hovers around enigmatic wispiness and threshold articulations. Scrapes, scribbles, taps and busy rummaging transmit from Bridget Carey’s viola, Anton Lukoszevieze’s cello, Nancy Ruffer’s flute, Simon Limbrick’s percussion and Philip Thomas’s piano. The result is engrossing: a luminous wash over textured scrawl and discreet graffiti: a Cy Twombly canvas in sound.”
