I can't stop listening to Arnie Schoenberg and His Second Viennese School. It's Lulu's death-shriek that gets me every time. Which diva is responsible for this thrilling rendition? It's not Teresa Stratas on the Boulez recording. Evelyn Lear on the old Karl Böhm set? ... Tom Hartley writes: "Maybe it's Charo."... David McIntire, a Kansas City composer, thinks it might be Helga Pilarczyk, on Antal Dorati's old recording of the Lulu-Suite on Mercury, although he doesn't have the recording handy to check. Anyone?
