Dude, there is a difference between heavy metal and death metal ...
Heavy metal: Iron maiden, motley crue, Judas priest, KISS etc
You dont know how many people between the age of 35 and 45 used to listen to that kinda music.
Every time i wear older bandshirts some adults start to talk to me about that period (mostly in shame), but just to give you some example:
- My boss (owner of a big mall), likes iron maiden and used to be a drummer in a band.
- Teacher, used to be a singer a band that did covers of kiss/europe/etc.
- The father of my girlfriend, he has a bunch of judas priest vinyls in his closet.
- Father of friend showed me pictures of him and his friends having their faces painted like KISS.
Death metal is noise indeed, but its some damn good noise
But anyway, back ontopic:
I usually dont disturb my parents with my music, especially if its death metal etc. They dont like it, i think.
But since i'm a big fan of 80's metal and i play that a lot, they sometimes ask me what song im playing (on guitar) cause they recognize it.
