About Alexander Tcherepnin
Alexander Nikolayevich Tcherepnin (Russian: Алекса́ндр Никола́евич Черепни́н, romanized: Aleksandr Nikolayevich Cherepnin; 21 January 1899 – 29 September 1977) was a Russian-born composer and pianist. His father, Nikolai Tcherepnin (pupil of Nikolai Rimsky-Korsakov), and his sons, Serge Tcherepnin and Ivan Tcherepnin, as well as two of his grandsons (sons of Ivan), Sergei and Stefan, were composers. His son Serge was involved in the earliest development of electronic music and instruments. His mother was a member of the artistic Benois family, a niece of Alexandre Benois. Tcherepnin invented his own harmonic languages. In 1925 he won the Schott Prize with his Concerto da Camera, Op. 33. The Singapore Symphony Orchestra was the first to record his complete symphony cycle, conducted by Lan Shui.
