Viennese composer Luna Alcalay continues to enrich the solo instrumental repertory, on this occasion with a short piece for flute in which she exploits, with her customary mastery, the instrument's rich expressive potential. Skilfully judged variations of dynamics, phrasing, attack and tone colour, often in close succession – en passant ("in passing"), as the title suggests – all combine to create an eight-minute journey full of shifting light and atmosphere.
