I'm surprised I haven't shared Dvořák's New World Symphony before! Dvořák, who was from Bohemia, composed it when he was director of the National Conservatory of Music of America in New York City (1893). He returned to Bohemia in 1895, but this symphony is an exquisite memento of his time in the "new world."
Carnegie Hall has a "Listening Adventure" for young audiences about it.
