April 18 1909 (Julian calendar)

Satina noted that this was the 6th Symphony Concert of the season for the Moscow Philharmonic Society, and that it was the first performance of Isle of the Dead. Rachmaninoff substituted for Arthur Nikisch, who was ill. Satina added that ‘he accepted only two concerts and rushed back to Dresden’, seeming to place doubt on whether Rachmaninoff similarly substituted for Nikisch in a third concert on April 27 (Julian calendar), however Rachmaninoff's participation in that concert is confirmed in other sources, and is noted by him in correspondence to I.V. Lipaev on March 19 (Literaturnoye nasledie, vol. 1, p. 474). Martyn listed the later concert. LoC, Sergei Rachmaninoff Archive, ML31.R33, Papers of Sophie Satin, boxes 82-89.
