In 1575, Orlando di Lasso, the ingenious Munich court composer, created an unrivaled setting of the Requiem texts for four a cappella voices. This version for four mixed voices was considered the original version until recently. In 2014, a previously unknown copy of the work was discovered in the Augsburg State Library, which is set a fifth lower and contains a setting of the Dies Irae sequence that had previously been lost. The dating of the manuscript suggests that it is most likely the original version of the work.

The unusually low register makes the work a profound sound experience that finds its climax in extensive meditation. On this evening, the individual parts of the Requiem are accompanied by works by Scandinavian composers that reflect the liturgical text.
