Luigi Russolo reading

I found this article to be dry and dense.  I did not enjoy it, however it did have some interesting points and ideas.  "Ancient life was all silence. In the nineteenth century, with the invention of the machine, noise was born." This is an interesting idea, however I completely disagree with it.  Nature, even ancient nature, has sounds.  Weather, animals, tree branches falling, wind rustling leaves, the crash of the ocean against the sand; all of these and more are different sounds that can be heard by nature.  However, the invention of the machine did have a direct effect on the sounds heard in nature.  For example, I was walking back to my apartment today and I heard a bird mirroring the sounds a car alarm typically makes.  While this brought me some amusement, after reading this article I wonder how many other natural sounds have been effected by the invention of the machine.
