Sillis is excellently partnered by the mature Carlo Bergonzi as Edgardo, elegant and outraged, and the brutal Piero Cappuccilli as the cruel Enrico. Justino Diaz is the cast's woolly weak link as Raimondo. The lamented Thomas Schippers leads a tight, exciting, as-if-it-were-new performance, with every cut opened (including a thrilling Wolf's Crag scene), and he uses the glass harmonica Donizetti wanted in the Mad Scene, which adds just the right amount of eerieness. Of course you can't do without a Callas Lucia, but Sills is just as necessary (as, let's face it, is Sutherland). It's great to have this set available again.
