Sergei Rachmaninoff is widely regarded as one of the great pianists of the twentieth century. In a research project that has stretched over two decades, I have compiled data on Rachmaninoff’s performance career, comprising research in archives as well as published sources in Russian and English languages. The resulting Rachmaninoff Performance Diary has been publicly available online since 2011. A missing link in the data has been the complete programmatic details of over 1,080 solo recitals. In 2006, I discovered research that was apparently unrecognized in its completeness in an archive of the Library of Congress, undertaken and donated by Rachmaninoff’s sister-in-law, Dr Sophia Satina. In this article, I examine the details of the 1924/25 season, which was a critical time for Rachmaninoff: after the collapse of his personal fortune caused by the Russian Revolution, he at last had achieved sufficient success and financial security from his hectic touring to allow him to return to composition the following year, his ‘sabbatical’ break of 1926. From the data, a clearer picture emerges of how Rachmaninoff varied his repertoire in his many concert appearances and recording sessions, showing how frequency of performance and, in instances, apparent self-assessment of his own music, were key factors.
