The Andalusian musical repertoire has a profound relationship with spiritual texts. Vocal techniques have been refined since the Middle Ages. This forms a rich tradition that can be heard even today around the Mediterranean Sea, from intimate settings in holy shrines to open-air concerts in old medinas. The Moroccan vocalist Marouane Hajji is the genre’s greatest talent. He is the driving force behind the revival of the spiritual repertoire among the younger generation of the Arab world. During ‘Spiritual Songs’, both the Eastern and the Andalusian variants were performed, including mystical songs from the distant Moorish-Andalusian past.
