My favorite type of music is heavy metal!
I love the earliest heavy meatl music from the late 60's UK!
What were some of the bands that played in the 60's in the UK? I'm not too familiar.
Some of my favorite groups include Led Zeppelin, Black Sabbath and Deep Purple.
Black Sabbath is probably the most recognizable of the three you listed.
I think they're all pretty well known. But Black Sabbath was not popular at all when they first debuted. They got lots of negative reviews.
