I am really not a fan of Heavy metal music.Though I would love to know how they play
Heavy metal rock music is great.
What makes it great?
I think Led Zeppelin and Deep Purple have interesting acts.  They founded the genre, too.
When was it founded by them?
In 1968, i think Black Sabbath was a founder as well.
Usually that genre of music is too loud .I love blues and jazz music.Do you know them?
That's understandable as jazz is seen by many as America's classical music.
