When people hear the words “heavy metal”, these words usually come to their minds: black eye-liners, weird emo haircuts, and black outfits. But this genre of music is more than what meets the eye.
Heavy metal or metal is a genre of rock music that was introduced in the late 1960s and early 1970s. The bands created heavy metal with thick and massive sound which is characterized by highly amplified distortion, guitar solos, and emphatic beats that produce loudness.
Oftentimes, heavy metal performances are associated with aggression and machismo.
In 1968, heavy metal bands such as Led Zeppelin, Black Sabbath and Deep Purple attracted large number of audience although they were often judged by critics because of their loud and hard-to-the-ear-noisy music.
During the mid-1970s, Judas Priest started an evolution by removing much of its blues influence.
Motörhead introduced a punk rock sensibility by increasing its speed. British heavy metal bands such as Iron Maiden and Saxon followed in a similar path during the late 1970s and fans were known as “metalheads” or “headbangers”.
During the 1980s, glam metal became popular with groups such as Mötley Crüe, Poison, Metallica, Megadeth, Slayer, and Anthrax.
Other extreme subgenres of metal such as death metal and black metal also broke into the mainstream.
Since the mid-1990s styles, the definition of heavy metal music have expanded. These include groove metal with bands such as Pantera, Sepultura, and Lamb of God and nu metal with bands such as Korn, Slipknot, and Linkin Park.
