Mozart: The Impresario
(Previn, Grist, Raskin, Lewis, Milnes, English Chamber Orchestra; RCA Victor LSC-3000). A high-powered cast unleashes its talents on Mozart’s modest little Schauspieldirektor with engaging results. The four-number opera is sung in English, and the one complaint is that the singers are a long way from pronouncing their words clearly and carefully. Without the printed English text we’d be lost.
