Sidor Belarsky was a Russian-born American bass, active in opera, concert and synagogue music. He became known for Russian, Jewish and operatic repertory.

In the Pristine catalogue he appears in Toscanini’s 1944 NBC recording of Beethoven’s Fidelio, with Eleanor Steber, Jan Peerce, Rose Bampton and Nicola Moscona.

Belarsky’s singing brought dark bass colour and clear theatrical presence to Beethoven’s moral drama.

His page is justified by secure identity and catalogue context. Belarsky gives the Toscanini Fidelio shelf a strong lower-voice foundation.
