my favorite type of music is heavy metal

Metal takes influence from many genres such as blues rock. It's also known for it's overall loudness and amplified distortion.

do you know when and where heavy metal actually started?
1_Wizard
Yes, actually. It developed in the late 1960s and early 1970s, largely in the United Kingdom, believe it or not.

to me heavy metal started with Black Sabbath but I guess there were bands before them
1_Wizard
You're right that there were other bands, but Black Sabbath was influential as well. They formed in Birmingham in 1968

other than Black Sabbath, I cannot think of any other band during that time period
