The Salón Los Angeles is the oldest dance hall in Mexico City. The classic 1930s ballroom is located in a working-class neighborhood near downtown, and every week, it sees dozens of well-dressed couples of all ages moving to an orchestra of saxophones, trumpets, trombones, clarinets and percussion instruments.
The music is called danzón, and it was born in Cuba in the late 1800s. By early in the next century, it had couples gliding in set patterns in a kind of formal square dance. It was huge. But, like popular music in every era, danzón was eventually replaced by more modern styles.
