I watched this film firstly when I was 4 or 5 years old. I didn't really know what I was watching in the early 90s. I just remember that half was animated and half was a horrible barren wasteland with not many people and a man playing piano wearing a gas mask. The song played by the man wearing a gas mask whilst the woman watches is called Veni Gabriel by Horacio Moscovici who was by chance in Buenos Aires, whilst playing at a bar, approached by the director who happened to be there. He was asked to write the score to the movie. This was in 1986 or so. Since google existing, I looked up this movie and watched again and how it bares a resemblance to what happens to day. I just got off the phone to Horacio Moscovici now where he is in Argentina. I have been playing piano for 25 years or slightly more now.
It is strange how a movie can be made but as time passes have a little more meaning than it did before. Sometimes humanity isnt ready for movies made yet. Sure the movie is low budget but then again so are a lot of the best theatre performances. Sometimes you have to put aside the fact that there isnt complicated CGI sequences like Lord of the Rings or the pyrotechnics of Saving Private Ryan and see a movie for what it is.
Look up Del Nido al Vuelo - Horacio Moscovi - the whole album is brilliant stuff and piano that is not your usual Bach or Beethoven.
