Hickox's recording of "Dona nobis pacem" is excellent (I rate it second, just a shade behind the late Robert Shaw's on Telarc); the singing is first-rate throughout, and the finale is a roller coaster of emotions, from fear to joy to quiet dignity. Yvonne Kenny in particular handles her solos effortlessly.
Hickox's 'Sancta' will be, almost without question, the standard for any future recordings of the work. Using all the forces RVW recommended--especially the organ--the net result is incredible: the finale, "Heaven and earth are full of thy glory," is simply overwhelming, an incredible onslaught of sound, followed by one of the great surprises in all of 20th century music. And there are moments of great beauty as well: "Babylon the great is fallen" is a hushed lament (handled with even more skill than Walton's setting of the same text in "Belshazzar's Feast"), while "And I saw a new Heaven" is simply ravishing.
I recommend this CD highly and without reservation.
