Par HARVEY JONATHAN. Andrew Porter says '. . . a stirring and beautiful adventure. . . He has written some of the most ardent love music since Messiaen's, and love music finds its place in the opera. . . There is also music of pain and despair. Bell sounds, chants, choruses, electronics, swelling harmonies, sharp-focus solo lines fill the theatre with deep, ever-changing ever-stirring music.' The Observer, 13 June 1993/ Répertoire / Livret

The Libretto of Monteverdi's opera The Coronation of Poppea edited by Alan Curtis.

Libretto for Caritas an Opera in Two Acts.Caritas’ is in two acts the first consisting of 12 short scenes the second being a continuous scena.The overall form of the opera retains the architecture of Wesker’s stageplay but alters the proportions in order to create a musically dynamic form. While each scene of the first act is centred around a specific pitch the second act is a Passacaglia whose ‘ground’ is a Cantus Firmus eachrepetition of which begins on a different note from those of its previous statements. These large-scale architectural features are both reflected in and derived from the musical material itself.
