The way he ended his post reminded me very much of the motet we'll be singing during the Third Hour at Chapel of the Cross: Tomàs Luís de Victoria's Popule meus, which is an exquisite piece. Compline choir sang it as Introit last Sunday.
Popule meus, quid fecit tibi?Give Jason's post a read. You'll be glad you did.
Aut in quo contristavite?
Agios o Theos.
Agios athanatos, eleison imas.
Sanctus et immortalis,
In the meantime, here's a YouTube video I stumbled upon. Exquisite! This is The Reproaches, sung at St. Thomas 5th Ave., New York. It incorporates Victoria's Popule meus.
