I like to listen to heavy metal music which is a genre of rock that developed in 60s and 70s.
I like rock music, but I'm not sure I've listened to heavy metal. What were some of the more popular bands?
The early ones were Led Zeppelin, Black Sabbath and Deep Purple.
Oh, I like Led Zeppelin! They did a ton of great music. Is heavy metal still popular?
Yeah although it has evolved. In the 1980s glam metal was popular with Motley Crue and Poison.
