Heavy metal music is often described as generating a thick, massive sound that includes guitar solos, amplified distortion, complicated beats and an overall loudness. Basically, heavy metal music was first developed in the late 1960’s with famous groups like Black Sabbath and Led Zeppelin. The lyrics of this type of music focus on depressing subjects which usually includes death, war, and personal trauma. There are some forms of heavy metal music that are extreme wherein they often concentrates on lyrics that are aggressive, while there are also others that are more on philosophical themes. One common theme used in metal is the thought of doing what you want.
Take note that heavy metal music is extremely masculine, therefore, there is no usual dancing that happens just like those from other concerts. Most of the audience will be banging their head or doing some arm gestures. There are also other people that are fond of stage diving or even crowd surfing. If you are thinking of listening to it, you should have an open mind.
