With its seamless blend of twelve male voices, ranging from countertenor to bass, the San Francisco-based ensemble Chanticleer, celebrates the life of their founder Louis I. Botto on the 10th anniversary of his death. Five composers create a mass that evolves organically, as if written by one hand and the ensemble brings it to life. Using Gregorian Chant as a foundation this Mass evolves organically, as if written by one hand. These composers bring international prestige to the project as well as vastly different life paths and points of view. Israeli-born composer Shulamit Ran wrote the Credo to the Hebrew text "Ani Ma'amin." Well-known television composer Douglas Cuomo contributed the Kyrie. Turkish-American Kamran Ince composed the Gloria section in to a sufi text, while Ivan Moody, drawing from the Greek Orthodox tradition, delivered the Sanctus. The Irish folk and medieval music-influenced composer Michael McGlynn (Anuna) composed the Agnus Dei. To seamlessly travel from one composer to the next, Chanticleer offers haunting and beautiful pieces by Gesualdo, Part, Binchois, and Gabrieli.
