This new ”Mass of Light” is characterised by a special tonal language. An expressive archaic vocal style is combined with a solemn classical charm and slightly popular nuances. The light of the human quest, of the assurance of faith and divine eternal joy form the message of the Missa Lumen – a Mass that moves performers and the audience alike. With its scope for variant performances, the Missa Lumen is a versatile choral repertoire item for the annual calendar of church music: vocal-instrumental or a cappella.
