January 24 1916 (Julian Calendar)

Neither Satina nor Apetian noted this concert, in which Rachmaninoff's role was limited to accompanying some of his songs in an encore. The concert was the 6th of Koussevitzky's season, and is mentioned by Keldysh (p. 404) in regard only to Nezhdanova's participation, without providing further program details. Keldysh indicates that Rachmaninoff's role in the concert was not advertised, and that the audience was surprised when he seated himself at the piano to accompany Nezhdanova's encores. The review by Yury Engel in Russkiye Vedomosti on January 27 notes: 'В псполненных ею сверх программы романсах Рахманинова аккомпанировал сам композитор, так совершенно, как только он умеет' ['In the additional Rachmaninoff romances performed beyond the scheduled program, the composer himself provided the accompaniment—with that consummate mastery only he possesses']. It is not known which songs were performed as the encore.
