The 1970’s modified the music industry, introducing rock and roll, disco, and heavy metal. Although, 70’s music did pick up a little bit of style and tune from the 60’s, it was still a whole new decade of music. There were many different artists who lead the way in music including Led Zeppelin and Aerosmith, who were some few who first started playing heavy metal. 70’s music did not include just rock and roll, but a wide variety of genres and emotions in music. According to “Getting Heavy”,by Matt Annis, heavy metal was the “dominant form of rock music in America”. Heavy metal would be described with hard drums, loud guitar riffs, and extreme vocals. This form of rock sprouted quickly and became the most attractive music in the United States.
