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 choir's follow-up disc to their highly successful recording of Rachmaninov's All-Night Vigil, which was Gramophone's Recording of the Month in February 2013. For the Missa A Cappella alone, this album will likely become a seminal recording of Rautavaara's sacred choral repertoire. Those wishing to become more familiar with this challenging, nuanced literature would do well to add this CD to their collection. --John Guarente, Choral Journal, Nov 2014
