Joining the tradition of a Catholic mass with the passion of Flamenco music, Spanish performer-composer Paco Peña manufactures a unique concert experience, leading a 20-voice choir, a trio of guitarists (Pena José, Diego Losada and Juan Jimenez) and an all-star group of singers (Dieguito, La Susipaco, Guadiana and El Chapparo). The result is a moving and memorable blend of musical styles that's as clever as it is controversial.
