Born in 1947, Salvatore Sciarrino has been delighting and perplexing his audiences, often at the same time, ever since the mid-60s, though his reputation has long since spread beyond European avant-garde circles, particularly with the opera Luci miei tradici and its stagings in Brussels, New York, Salzburg and Berlin. The basic premises of Sciarrino’s language explore the limits of perception, the borderline between sound and silence, and the abstraction of gestures and forms from the tonal contexts that supply them. ‘I don't write music, I write a psychological experience,’ Sciarrino he declared, and his output certainly resists description or classification except insofar as it takes its place in a grand tradition of Italian postwar experimentalists in the laboratory of sound, headed by figures as diverse as Luciano Berio and Luigi Nono.

Even at the level of his works for orchestra and the stage, Sciarrino writes with an immediacy and intimacy of expression which finds its natural home in the kind of chamber ensemble works recorded here. Scored for flute, guitar, bass clarinet and violin, the album’s title work dates from 1986 and lives up to its title by discovering how many shades of sound can be found near the border with silence, a sonic analogue to a Rothko painting or an Agnes Martin drawing. Vagabonde blu makes full use of the accordion’s potential to set weightless and ceaseless waves of sound in motion. By contrast, the scoring of alto flute, cor anglais and bass flute makes Muro d’orizzonte a study in furtive attacks and explosions. The most recent work is Alba meònia from 2020, receiving its first recording on this album, and scattering its timbres across a still wider soundscape through the diverse scoring for flute, violin and guitar.
