«After university, Sobinov performed military service and then began to practice law. He also studied singing in Moscow with professors Alexander Dodonov and Alexandra Santagano Gorchakova, who, in 1897, suggested that he attend an audition at the city’s Bolshoi Theatre. He did well at the audition, obtaining a Bolshoi contract for an initial period of two years. This contract would lay the foundation for a subsequent singing career of extraordinary success.»
