The Five
The group began to meet in 1856. This was before Anton Rubinstein founded the St Petersburg Conservatoire.  Music at the Conservatoire was taught in a European way.  This is what The Five, together with the music critic Vladimir Stasov, were against.  However, in later years Rimsky-Korsakov taught at the Conservatoire, and Rubinstein who had left in to concentrate on his career as a pianist, often used ideas from Russian folk music.  The difference between the two parties had become blurred. By the 1880s The Five were drifting apart because they each had developed their own personal styles.  Apart from Cui, whose music is not often heard today, the members of the group influenced or taught many of the next generation of Russian composers, such as Alexander Glazunov, Mikhail Ippolitov-Ivanov, Sergei Prokofiev, Igor Stravinsky, and Dmitri Shostakovich.
