Options: Dispersions and Volatility Spreads

Prologue: 1915

Nearly a 100 years ago, D.W. Griffith released a classic of early cinema: "Birth of a Nation".

It was explicitly racist ("The Clansmen" was its alternate title), and it is quite something to think what society must have been like in 1915 to enable wide release of a film like this. It was also a stupendous cinematic achievement and more or less defined the genre of Epic filmmaking.

In German, "Birth of a nation" translates as "Geburt Einer Nation".

Fast forward: 1985

Freddie Mercury pens the song "One Vision" for Queen's performance at Live-Aid. A paeon to peace and tolerance and respect, it became an instant classic after a headline performance in front of the massive Wembley audience.

 
    One man one goal -- one mission 
    One heart one soul -- just one solution 
    One flash of light yeah --  
    One God  
    One vision... 
  
    One flesh one bone -- 
    One true religion 
    One voice one hope -- 
    One real decision

Two years later, on the sunny side of the Alps, Slovenian (then still Jugoslavian) artists organized as the Neue Slowenisch Kunst released the single Geburt Einer Nation. The song mated a growling German bass-baritone chanting to a foundation-shaking industrial beat and synthetic Wagnerian orchestration. The video had members of Laibach parading about in what appeared to be Nazi uniforms, saluting in the well-known manner and generally looking and acting quite disturbing.

   Ein mensch, ein ziel -- Und eine weisung 
    Ein herz, ein geist -- Nur eine loesung. 
    Ein brennen der glut -- 
    Ein gott 
    Ein leitbild 
  
    Ein fleisch, ein blut -- 
    Ein wahrer glaube 
    Ein ruf, ein traum -- 
    Ein starker wille

One song: one version loved, one version banned.
