Two amazing bits of music.
Here is one of the loveliest motets I've heard in a long time, in Italian: Leo XIII's poem Neve non tocca, to the Immaculate Conception, beautifully set by Father Lorenzo Perosi (a dear friend of St. Pius X and composer to the Vatican during his pontificate.)
And here is Edvard Grieg's marvelous Ave Maris Stella.
