The mystical extasy of the virtuoso, hypnotizing vocal music of 12th-century Benedictine abbess Hildegard of Bingen became immensely popular during the hippie wave of the 1970s. At the Festival de Saint-Denis 2010, Ibrahim Maalouf performs an original composition inspired by Hildegard's music, including a children's choir and brass instruments. The choir is led by the brilliant conductor of Radio France, Sofi Jeannin.
