Although Dmitri Shostakovich had already premiered a number of
works before then, his music achieved international recognition
with the premiere of his Symphony no. 1, op. 10. Written as his
graduation piece from the Leningrad Conservatory, Shostakovich's
first symphony debuted in Leningrad in May 1926. A year later, the
symphony was premiered in Berlin, and major conductors (including
Toscanini, Berg, and Klemperer) tackled the work.
