When I heard metal for the first time, it was just noise. I was unable to discern any musical elements at all.
However, with time, it grew on me, and I found myself liking it after a while. It wasn't noise anymore. It was music, and it was good. Very good.
Problem:
What used to be heavy wasn't heavy after a while. I needed more. I needed heavier. I found genres like death metal and black metal and my life suddenly had meaning.
There was so much to listen to, so many complex patterns, ah!
Drums, guitar, bass, vocals (no, it doesn't matter whether or not you understand what they're singing, vocals are like an additional instrument), sometimes keyboards. When all of these are played skillfully simultaneously, whoaah...
I've been listening to metal for about three years, and I've already hit rock bottom when it comes to brutality. When you've gotten used to bands like Anaal Nathrakh and Brain Drill, you've explored the spectrum, and at this point my taste in music was "stabilized".
Today, I listen to all types of metal.
I like it's because it's so stimulating. So is classical music. That's why I love Beethoven, too.
My mom really doesn't know what to think. Modern shit noise and 19th century symphonies.
