Many contemporary composers were strongly influenced by the vocal music of the Middle Ages and the Renaissance. The award-winning vocal ensemble Singer Pur pursues these diverse connections on their fifth CD. The result is a fascinating forensics that opens new worlds of sound and provides new auditory impressions. Wolfgang Rihm's cycle of seven passion motets dedicated to the group Singer Pur were already recorded in part on OC 354, with the first recording of the remaining three motets now completing the cycle. The three Rihm motets, which came into being in 2005 and 2006, and Arvo Pärt's Memento step into a colorful dialogue with works from Orlando di Lasso and Flemish church musician George de La Hèle, who died in 1586 at the age of 39. Moreover, bridges between Lasso and de La Hèle are knocked down because de La Hèle referred to Lasso's motet "Quare tristis es" in his missa of the same title and reinterpreted it.
