This collection of sacred music spans the centuries by interspersing contemporary works with the Laudario di Cortona, Italy, part of an extensive collection compiled during the 13th century. They are performed in arrangements by Paul Hillier which celebrate their very distinctive ambience. The six pieces by Arvo Pärt are relatively recent and exemplify his intensely communicative musical language, not least when setting Church Slavonic. The text of Julia Wolfe’s arresting Guard My Tongue is derived from Psalm 34, whilst Caroline Shaw, the youngest recipient of the Pulitzer Prize for music, uses extended vocal techniques in her setting.
