On Feb 13, 1867 the “Blue Danube Waltz” by Johann Strauss Jr. was performed for the first time at a public concert in Vienna, Austria.
The first son of Johann Strauss Sr., his father forbade him a musical career but the younger Strauss cared more for his violin lessons, than his schoolwork. He would become his father’s most serious competitor. His “Schöne Blaue Donau” is kind of an unofficial anthem for Austria to this day & is traditionally performed each year at the New Year’s concert in Vienna.
