Japanese hip hop+

I wrote about hip hop music in Israel and other countries in one of my essays which I submitted in this week. The essay's theme was a message in Palestinian hip hop bands. When I dealt with hip hop in Palestine and the USA,all of a sudden I became curious about Japanese hip hop. I knew some rap songs in Japan, and I like them because the rhythm and sound are good. However, I've never concerned about the lyrics and messages in these songs.
I searched a rap song which has a strong message in lyricsby surfing the Internet. And I found it.
At the beginning, I thought that there must be a song related with The Japan Earthquake. So I started to search by keywords "The Japan Earthquake" and "hip hop." I could find a rap song soon.
I really recommend to hear this song "Apocalypse Now" by King Giddra. Listening to its lyrics, you can't help smiling. Actually, I am not sure about the current situation in Japan after the earthquake. I experienced the planned blackout and continuing aftershocks. But do people in Japan still feel a strong fear? I know there is the danger of a nuclear radiation. This is a long long-term problem.
Anyway, in the lyrics of this song, rappers express a fear and anger, and protest against the electric company and government.  I found rapping is a great tool to protest against the authorities because it represents people's emotion and opinion.
Also, I recommend a documentary film "Slingshop hip hop" on the Palestinian hip hop artists. I think it is difficult to watch it online, but you can buy it from its homepage. It tells us a severe situation surrounding the Palestinian within Israel, Gaza and West Bank, and rappers who wants to convey a message to tell about the situation in their homeland, and their anger, and hope.
