Notes
Satina indicates that this was a chamber music concert, however she does not offer information on which chamber works by Rachmaninoff were played. However, Apetian recorded the works that are indicated, though also noting that it was not clear which of the Etudes-Tableaux were played. Keldysh (p. 403) notes that the violinist and cellist were local musicians. LoC, Sergei Rachmaninoff Archive, ML31.R33, Papers of Sophie Satin, boxes 82-89.
