Effect on Animals
"A student named David Merrill subjected mice to the music of a heavy metal band called Anthrax 24-hours a day to discover how it would affect their ability to learn new things, but instead of completing Merrill’s maze, the heavy metal mice all killed one another.
In a subsequent experiment in which the mice listened to heavy metal music for 10 hours each day, they did not become homicidal, but they did grow worse at solving the maze than they had been when they first encountered it. However, research indicates that reactions to music are shaped by whether or not it is the genre of choice. It is highly unlikely that if the mice had a musical preference at all, it would have been Anthrax."http://cognitive-psychology.suite101.com/article.cfm/psychology_of_heavy_metal_music
Three mice, a card board maze and Obscura could send shockwaves in the scientific community with documented improved performace. 12-24 hours of Anthrax would cause similar results in most human subjects.
