I really like heavy metal music, some of my faves are Iron Maiden and AC DC. do you listen to it? 
Yes I love it! It started in the late 1960's and early 1970s mostly in the UK.
Wow in the UK? I never would have thought that it originated from another country, I see heavy metal as a mostly american thing. 
Around 1968, three of Heavy metal's most famous bands, Black Sabbath, Led Zeppelin, and Deep purple were founded.
Thats pretty sick, who knew that heavy mental existed in the 1960's. What are some of the most popular heavy metal bands of today? 
I'm not sure but Heavy metal lyrics have a massive sound with amplified distortion, lots of guitar solos and just an overall loudness.
Yeah they are usually really loud especially at concerts, Can you tell me more about heavy metal music? 
There are different genres of heavy metal. There's alternative metal which came about in the mid 80's. It's a mixture of heavy metal and alt. rock.
