Since the 1630s, the psalm Miserere mei Deus has been sung at dawn during Holy Week in the Sistine Chapel while the Pope kneels in prayer. This contemporary version, recorded in the spectral grandeur of Osnabruck Cathedral, adds new material composed by Vladimir Ivanoff to the ethereal harmonies of the Osnabruck Youth Choir and the elegiac brass tones of the cornetto, recreating the mysterious beauty of this sacred classic.
