Excerpt from Alexander Nevsky at google video. Music composed by Sergei Prokofiev. Eisenstein and Prokoviev worked very close on creating sound image relations in this work.
"Alexander Nevsky is a film directed by Sergei Eisenstein and Dmitry Vasiliev, produced by Mosfilm and released in 1938 with Nikolai Cherkasov in the title role...
The film was the first of Eisenstein's to use sound. The film's score was composed by Sergei Prokofiev, who later reworked the score into a concert cantata."
