"The melody to Herzlich tut mich verlangen, "My heart is filled with longing," was written by the German Hans Leo Hassler, but it is best known as the melody to the hymn "O Sacred Head." The medieval St. Bernard of Clairvaux is credited with the text to this great passion hymn. It was one of J.S. Bach's favorites, and he wrote many settings for it, including this one for organ, and most famously in several different choral versions in the St. Matthew Passion."
"Le banquet celeste, or "The Heavenly Banquet," is the first of Olivier Messiaen's published organ works. This quiet, meditative piece is both a reflection on the events of Holy Thursday and a celebration of the eternal heavenly feast to come. Throughout, a slow theme grows and develops in the strings--the "celestes"--which has an eternal and heavenly peace to it, while the pedal plays short striking notes, which the music indicates as representing Christ sweating drops of blood in the Garden of Gethsemane. I first heard this piece at the very first Holy Thursday Mass I ever attended, and it is a large reason why I am Catholic today. I hope it is evocative for others."
