This is the Day!

On this eighth day, the octave day of Easter, here is a twofer: Byrd and Palestrina's renditions of the Easter antiphon, "This is the day the Lord has made; let us rejoice and be glad in it. Alleluia!" (Sorry about the ad; the singing of King's College Choir will more than make up for the intrusion. If you cannot see the video, click here for it.)
