In the biographical film Maestro, Leonard Bernstein’s dramatic 1943 Carnegie Hall debut conducting the New York Philharmonic, filling in at the last moment for Bruno Walter, receives a masterful cinematic treatment.

But the first time Bernstein wielded a baton in public took place on today’s date in 1939, when Lenny was still a student at Harvard and conducted his own incidental music for a student performance of the ancient Greek comedy, The Birds, by Aristophanes.

The play was performed in the original Greek, and since almost no one in the audience would understand what was being said, the production relied on visual, slapstick comedy and Bernstein’s electric music to bring the ancient text to life. Bernstein’s score referenced everything from sitar music to the blues to get the humor across. The student production was a surprise smash hit. Aaron Copland and Walter Piston were in the audience, and photos even appeared in Life magazine.

Bernstein recycled one of his bluesy songs from The Birds into his 1944 musical On the Town, but the rest of the 1939 score was never published, and only revived in 1999 for a performance by the EOS Orchestra in New York, and to date has never been recorded.
