Daser was the choirmaster in Munich when Lassus joined the Bavarian Court Chapel as a tenor, putting Daser rather in the position of Salieri in Venice: a good composer unlucky enough to find himself coupled with one of world stature. Daser was offered an honourable compromise, taking the director's position in Stuttgart with a lifelong pension from the Bavarian ducal house. His music is being rediscovered, and this mass on Josquin's famous Marian piece is a very fine one.
