System of a Down 

A band with one of the most unique music styles ever, mixing Middle-Eastern and Armenian with Metal. Sometimes the music is calm, sometimes its angry and sometimes its crazy (like the song "Johnny"). Usually they scream a lot and then go calm, probably because their throats hurt.

There is meaning to System of a Down's lyrics, listen to "Boom!" and "Chic n' Stu" (though I doubt most of you droids couldn't interpret that song).
