Anatoly Lyadov
Rimsky-Korsakov, with Alexander Glazunov, Anatoly Lyadov and several other nationalistically minded composers and musicians, had formed a group known as the Belyayev circle, named after a merchant and amateur musician who became an influential music patron and publisher. Tchaikovsky spent much time in this circle, becoming far more at ease with them than he had been with the 'Five' and increasingly confident in showcasing his music alongside theirs. This relationship lasted until Tchaikovsky's death.
