Between Darkness and Light. A Mass for Amarcord’s 25th anniversary. It appears to be amarcord’s “personal Mass” for the ensemble’s 25th anniversary and “our mostserious reflection upon the world,” so tenor Wolfram Lattke. On the new album “Tenebrae,” the twotime prizewinners of the ECHO Klassik Prize look at the expanses of their repertoire and repeatedly captivate with their distinctive sound and breathtaking homogeneity. amarcord succeeds in forging an arch fraught with tension from early monody and polyphony through Renaissance polyphony by grandmasters such as Johannes Ockeghem and Thomas Tallis to contemporary pieces written expressly for the ensemble by Sydney Boquiren, Ivan Moody, and Leipzig composer Marcus Ludwig.
