Do you know that is a genre of rock music that developed in the late 1960s and early 1970s?
Yeah I really like rock. Can you tell me more about the genre?
Yea, we are actually talking about heavy metal music,  my wife does not it much because sometimes associated with aggression and machism
Oh I love metal. It is great music to relieve stress. My favorite bands are Metallica and Pantera.
Something special happened in 1968, guess? the most notable figures in the genre Led Zeppelin, Black Sabbath and Deep Purple were founded.
Oh yeah I love Sabbath and Zeppelin. Ozzie is still making music today!
The number of crowd that usually follow them is so shocking and sometimes brings criticism
Why would it bring criticism? Heavy metal is a great genre of music!
