Celsi tonantis

This is a substantial motet for SATTB voices by Johannes Regis, setting a Latin text of considerable poetic and theological scope. The music opens with a rich, imitative texture that gradually unfolds the grandeur of the text. The composer explores the complex relationship between Mary, the 'Mother of the lofty thunderer,' and divine power. The text draws on Marian antiphonary language and high Renaissance devotional imagery, depicting Mary's exalted status in heaven and her role as intercessor for those suffering in hell. Regis's setting matches the elevated subject matter with intricate vocal writing, demanding skilled ensemble work to navigate its contrapuntal demands and to convey the profound reverence of the Latin words.
