Rihards Dubra: Duo Seraphim
El León de Oro; Marco Antonia García de Paz

The anthem Duo Seraphim mixes the vision of the prophet Isaiah of the two seraphim who proclaim to each other before God the Trisagion, that is, the three times holy to God, together with a text of the First Letter of Saint John, in which he affirms the unity in the Trinity.
