Today in History - 1867

Strauss' Blue Danube Waltz was performed for the first time* at a public concert in Vienna, Austria. It was originally written as a male choral piece but after its performance as an non-choral work at the Paris Exhibition later that year, it became a sensation. Of course, a "modern day" reference was its use in 2001: A Space Odyssey.
*Some say the first performance was February 9, others February 15.
