Grammy© nominated guitarist/composer Alex de Grassi teams up with vocal duo The Real Sarahs on this traditional holiday song thought to have originated in Germany during the late 16th / early 17th century and later appropriated for the Roman Catholic Agnus Dei. Beginning with the traditional three part round between “sympitar” (sympathetic stringed guitar) and two voices, the arrangement then progresses into uncharted territory to yield a sparkly, contemporary twist to a Winter holiday classic.
