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?
