I rarely listen to choral music, but Spem in Alium takes one's breath away, showing Tallis's mastery of composing for the human voice. One listens and one wonders when on earth the singers breathe! But they do!
Listen to this music, listen in wonder at an orchestra of voices, and remember that it was written over four hundred years ago.
As our American cousins would say, "Awesome" This time they are right.
