Robert Stolz was operetta royalty, and his recordings with the Berliner Symphoniker and Wiener Symphoniker document the world of light orchestral music with unique authority. Across 12 CDs, this Sony Classical Masters collection brings together Stolz’s recordings of waltzes, marches, polkas and other dances by Johann Strauss I and II, Joseph Lanner, Carl Michael Ziehrer and others. These recordings date from the 1960s and 70s, some 70 years into Stolz’s career. “Stolz belies his years in no uncertain fashion,” wrote Gramophone of some of these recordings.
