Sills as Zerbinetta

A web site devoted to the late Beverly Sills has a treasure trove of material, including many free audio recordings--including her stupendous 1969 concert performance of Zerbinetta's aria in the original 1912 version of Ariadne. The tessitura is actually higher than in the revised version, which is itself a test of any coloratura soprano's mettle. This is the kind of thing that formerly would only be available to the intrepid acquirers of "private recordings." Worth the visit.
