Not so--many of them, like the Lassus recorded here, have lovely major-key part-writing and a sweet, tranquil air. The Hilliard Ensemble captures these qualities beautifully at the beginning of this disc: the first three tracks contain their most engaging singing in years. By track four, unfortunately, their dour streak emerges: however attractive Lassus's writing, it's difficult to stay involved with performances so aloof. Disappointment turns to serious frustration with Prophetiæ Sibyllarum (a set of verses purportedly prophesying Christ's birth). The astounding opening movement changes keys at least six times in 95 seconds; the reserved singing gives barely a hint that the music is at all unusual. For the Hilliard Ensemble at their best, try their Perotin CD; for a good example of Lassus in this mood, try the Penitential Psalms (Henry's Eight). To hear an engaging, enjoyable Renaissance Requiem, check out Manuel Cardoso or Duarte Lôbo, both by the Tallis Scholars. --Matthew Westphal
