I wrote a blog about the use of music for torture. A month later, Terry Teachout , one of my heroes, covers the same subject in the Wall Street Journal (pg. w12 2/14)
Terry speculates on why music can be such a source of pain. He argues that it can totally expand to all of space and all of time, particularly loud music. Terry finds what is believed to be a list of the music that is used for torture. I can appreciate why AC/DC, Aerosmith, Eminem, Dr. Dre, the theme from Barney the TV character and the Sesame Street theme can drive you nuts, but there are many more on the list I don't know.
I still argue that the Hippies pioneered music that is good for torture. The reason is that creating music while on a mind altering drug creates music that can alter the mind.
