Ondine continues its long-term collaboration with Einojuhani Rautavaara, the Latvian Radio Choir, and Sigvards Klava by presenting the world premiere recording of Rautavaara’s Missa a cappella. Being praised by Gramophone as an outstanding body of singers, the Latvian Radio Choir is one of the top chamber choirs in Europe. This is the choir’s follow-up disc to their highly successful recording of Rachmaninov's All-Night Vigil.
