January 4 1909 (Julian calendar)

This was likely the first performance by Rachmaninoff of his First Piano Sonata, which Threlfall and Norris (citing Oskar von Riesemann) indicate occurred at the Moscow Conservatory. The Sonata had first been performed by Konstantin Igumnov. Satina notes that this was the 2nd Chamber Music Concert of the Quartet of the Imperial Russian Music Society in Moscow. Vladimir Bakaleinikov, the violist in the quartet, would later conduct concerts in America with Rachmaninoff. LoC, Sergei Rachmaninoff Archive, ML31.R33, Papers of Sophie Satin, boxes 82-89.
