Belyayev circle
In November 1887, Tchaikovsky arrived in Saint Petersburg in time to hear several of the Russian Symphony Concerts, one of which included the first complete performance of the final version of his First Symphony and another the premiere of the revised version of Rimsky-Korsakov's Third Symphony. Before this visit he had spent much time keeping in touch with Rimsky-Korsakov and those around him. Rimsky-Korsakov, along with Alexander Glazunov, Anatoly Lyadov and several other nationalistically-minded composers and musicians, had formed a group called the Belyayev circle. This group was named after timber merchant Mitrofan Belyayev, an amateur musician who became an influential music patron and publisher after he had taken an interest in Glazunov's work. During Tchaikovsky's visit, he spent much time in the company of these men, and his somewhat fraught relationship with The Five would meld into a more harmonious one with the Belyayev circle. This relationship would last until his death in late 1893.
