Music in Reaction to 3/11

I am currently taking a class on the events and effects of Fukushima, and am now doing a personal study on how people worldwide reacted to the triple disaster of 3/11. As of now, the main reactions came in the form of Nuclear Power protest music, Charity concerts held all over the world to either spread the news of what was happening in Japan or to raise money for disaster aid in Japan, and that citizens of all ages who experienced the aftermath of Fukushima were able to deal with their situation through music, almost using it as a form of mental therapy.
