If you're in Washington tomorrow (August 15) and you want to hear some Renaissance music, the Choir of the National Shrine of the Immaculate Conception will be performing for the Feast of the Assumption at the High Mass at noon. The music will feature the 8-part Missa Salve regina (Gloria and Agnus movements) by Tomás Luis Victoria (1548-1611), the 8-part Magnificat setting by Luca Marenzio (1553/54-1599), and the 6-part motet Assumpta est Maria by Giovanni da Palestrina (1525-1594). We will also be singing the Hymn to the Mother of God (1985) for two choirs by John Tavener. The National Shrine is at the intersection of Michigan Avenue and Fourth Street NE in the District of Columbia. The choir will perform in the Great Upper Church.
