Several things about the voices here are so noticeable: first, how open, developed and properly registered they are, with no throatiness or constriction; secondly, and allied to that, how frequently Josefina Huguet, despite being a lyric coloratura soprano, plunges fully into her lower register - no wonder she could sing Wagner as well as the Queen of the Night - and, thirdly, how rapid are their vibratos; no wobble or slow pulse or sliding - superb. (Incidentally, collectors may know the Silvio here better as Don Pasquale in the 1932 complete recording also conducted by Sabajno, by which time Badini had moved into being a buffo basso - but still neat and light of voice - see my Donizetti survey. In his day, too, the tenor Antonio Paoli was more famous than Caruso.)
