what's "ROCK" really mean?

          I have opened this blog for several weeks. There are some of my friends come here and ask me about what rock music is. This makes me thinking about really deep. what is rock music? why people and bands choose rock music and play it so crazy? As a guitar player, I think the rock music not only gives you crazy feelings, but also bring the same believes for different group of people. Sometimes they may feel bad with there government, sometimes they may feel bad with the society. But the most important believe is trey can and they will shout it loudly to show themselves. it's really important for rock music. This is also important for rock music. If the rock music didn't include the mind, it's not rock music. Rock music is just a way for the group of people which have the same believe to communicate with each other. It's a way to understand each other , it's a way to show each other, also it's a way to get crazy!
