The article From no such thing as silence is about the American composer John Cage and his most famous composition 4’33. The piece was entirely silent which caused a lot of reaction leading to people thinking it was a hoax or joke.
John Cage believed that 4’33 the piece he worked the hardest on and described has his favorite was mostly about silence. Cage believed music should be free of the composers and musicians feelings. Instead let people see the sounds of their surroundings could be more interesting than any music they could find in a concert.
My personal opinion is while the sounds of peoples environments could be interpreted as art or interesting. I dont believe that it is more interesting or has more value than actual music.
