Tonight's In All Languages focuses on a survey or different time periods of Argentine Tango music. For the first hour, the focus was on the Golden Age of Tango, the 1940's. The second hour focused on what is classified as "New" Tango, which is simply orchestras in the last 20 years or so that have produced music in the style of the Golden Age. The final hour focused on "Nuevo Tango," a popular style of Argentine Tango music that incorporates new elements into traditional Argentine Tango music. It is prevalent outside of the Tango community for containing a beautiful mix of both traditional elemements as well as elements of other, seemingly unrelated, genres of music.
