This lovely performance from the Taylor Festival Choir presents two very different but both profoundly spiritual arrangements of the Catholic Mass. Both of these works display their composers’ strong Celtic roots. Celtic Mass by Michael McGlynn includes sections in Irish Gaelic between the traditional Latin phrases. Mass by James MacMillan sets the movements in English, and includes other liturgical texts that make the work acceptable for a stand-alone service. The Taylor Festival Choir, conducted by Robert Taylor, has earned itself a strong reputation for being one of America’s most prestigious professional choirs.
