Formed in 2012 by students at London’s Royal Academy of Music, United Strings of Europe brings together outstanding players from across the continent. The artistic director is Julian Azkoul, who leads from the violin, curates programs, and arranges music for the ensemble. For In Motion, Azkoul has arranged Boccherini’s atmospheric Night Music in the Streets of Madrid. Far removed both geographically and in mood is Maralinga, Australian composer Matthew Hindson’s powerful and haunting work featuring guest soloist Amalia Hall. The program opens and closes with works for string quartet, composed some 180 years apart in Vienna and New Zealand and heard in bespoke arrangements by Azkoul.
