text: Rachmaninoff spent his summer break in 1890 with the Satins at Ivanovka, their private country estate near Tambov, to which the composer would return many times until 1917. The peaceful and bucolic surroundings became a source of inspiration for the composer who completed many compositions while at the estate, including his Op. 1, Piano Concerto , which he completed in July 1891, and dedicated to Siloti. Also that year, Rachmaninoff completed the one-movement Youth Symphony and the symphonic poem Prince Rostislav. Siloti left the Moscow Conservatory after the academic year ended in 1891 and Rachmaninoff asked to take his final piano exams a year early to avoid being assigned a different teacher. Despite little faith from Siloti and Conservatory director Vasily Safonov as he had just three weeks' preparation, Rachmaninoff received assistance from a recent graduate who was familiar with the tests, and passed each one with honours in July 1891. Three days later, he passed his annual theory and composition exams. His progress was unexpectedly halted in the latter half of 1891 when he contracted a severe case of malaria during his summer break at Ivanovka.
  During his final year at the Conservatory, Rachmaninoff performed his first independent concert, where he premiered his Trio élégiaque  in January 1892, followed by a performance of the first movement of his Piano Concerto  two months later. His request to take his final theory and composition exams a year early was also granted, for which he wrote Aleko, a one-act opera based on the narrative poem The Gypsies by Alexander Pushkin, in seventeen days. It premiered in May 1892 at the Bolshoi Theatre; Tchaikovsky attended and praised Rachmaninoff for his work. Rachmaninoff believed it was "sure to fail", but the production was so successful the theatre agreed to produce it starring singer Feodor Chaliapin, who would go on to become a lifelong friend. Aleko earned Rachmaninoff the highest mark at the Conservatory and a Great Gold Medal, a distinction only previously awarded to Taneyev and Arseny Koreshchenko. Zverev, a member of the exam committee, gave the composer his gold watch, thus ending years of estrangement. On 29 May 1892, the Conservatory issued Rachmaninoff a diploma which allowed him to officially style himself as a "Free Artist".
