The song cycle Ayre for soprano and ensemble is one of the most remarkable and moving works of the 21st century. The experience of hearing this aesthetically radical piece for the first time is both enlivening and disorienting. The first time one hears it, it is difficult to decide whether the raw sounds, rousing rhythms and deeply penetrating lament are pop or classical music, or whether to classify the piece as folk music or to use some other category that has not yet been determined. It is a masterpiece in which Golijov weaves a web from strands of Arabic, Hebrew, Sardinian and Sephardic music, along with klezmer, flamenco and a mixture of electronic and traditional sounds. HERMESensemble combines Ayre with a performance of Adana by Wim Henderickx, a piece that evokes Indian moods.
