5.1. Origin of the term
5.1.1. Heavy Metal is widely attributed to novelist William Burroughs, its use actually dates well back into the 19th century, when it referred to cannon or to power more generally. It also has been used to classify certain elements or compounds, as in the phrase heavy metal poisoning. Heavy metal appeared in the lyrics of Steppenwolf’s “Born to be Wild” (1968), and by the early 1970s rock critics were using it to refer to a specific style of music.
5.2. musical
5.2.1. Mid-1960s British bands such as Cream, the Yardbirds, and the Jeff Beck Group, along with Jimi Hendrix, are generally credited with developing the heavier drums, bass, and distorted guitar sounds that differentiate heavy metal from other blues-based rock. The new sound was codified in the 1970s by Led Zeppelin, Deep Purple, and Black Sabbath with the release of Led Zeppelin II, Deep Purple in Rock, and Paranoid, respectively, which featured heavy riffs, distorted “power chords,” mystical lyrics, guitar and drum solos, and vocal styles that ranged from the wails of Zeppelin’s Robert Plant to the whines of Sabbath’s Ozzy Osbourne.
