"Haec dies" - William Byrd and Giovanni da Palestrina

It's Easter time!  Time for good music about Jesus' priceless gifts to all mankind.  I first heard this song on a CD that I purchased after a gorgeous concert by the Choir of Saint Thomas Church, New York City (at Christ Church in Cambridge, MA).

A translation of the text is:
"This is the day which the Lord hath made: 
let us be glad and rejoice therein. 
Alleluia."
[More words and translation here.]

This recording - by the Choir of King's College, one of my all-time favorites - includes two settings of the same text.  Enjoy!
