This is quite the best performance of Tallis's 40-part Spem in alium that I have heard. Sung by a constellation of singers, many of them familiar names from other well-established choral groups, it is a gripping realisation. The effect of the slowly moving harmonies is enhanced by a well-conceived and very positive use of dynamics. Precise entries, gently undulating rhythms that are wonderfully supple, and then those firm antiphonal phrases—one group of choirs answered by another at 'Creator coeli et terra'—raise the tension, until we twice almost miss a heart-beat at the well-placed rest before 'Respice'. Philip Cave's note on Tallis's recusancy background, his coded use of numbers and his acquaintance with influential members of the Catholic nobility (in particular the Duke of Norfolk, soon to be executed), gives the listener valuable insights into the whole corpus of Tallis's Latin compositions, particularly those of a penitential nature like the Lamentations or the Lenten responsory In ieiunio et fletu, and further heightens their poignancy.
That great motet, so central to the whole prgramme, is well supported by the four-part Mass and the delightful group of other pieces for various combinations of voices. The hymn 'Te lucis' with its alternating chant strophes sounding so very English (I don't want to say precious, but almost too perfect for what was, after all, just run-of-the-mill everyday chant!) has the tempo relationship of the chant to the polyphony just right, which is a tremendous plus, rarely achieved.
