Rock and roll is very real, mainly what you see and hear, or how you feel after hearing or seeing it, or your occasional inspiration.
As for the classification of rock and roll, this is hard to say. It can be roughly divided into hard rock, light rock, classical rock, pop rock, punk, britpop, garage, junk music, country rock and so on. But in terms of intensity and aggression, rock can be divided into: rock and metal.
The evolution of metal has long gone beyond the definition of rock, which means that metal is the largest branch of rock, almost equal to rock, hehe.
There are many kinds of metals: heavy metal, death metal, dark metal, industrial metal, agricultural metal, power metal, avant-garde metal, new metal (represented by Linkin Park), psychedelic metal, torrent metal and so on. However, there is a great debate about "Gothic Metal". Some people say that it is not a specific metal just because clothes and expressions are different, while others say it is an independent metal.
In fact, for us, as long as it sounds good, it makes no difference whether it is classified or not. After listening for a long time, you can naturally hear what kind and genre this is. What is rock and roll? Rock and roll means "writing your own feelings and thoughts and truly expressing your feelings in your own environment".
Many people have different views on Wang Feng. In fact, many of Wang Feng's songs are about feelings, which are very rare. Of course, if you really want to say it, I think Wang Feng sang the popularity of true feelings by rock and roll.
