Avenged Sevenfold (also known as A7X), is a metal core band from Huntington Beach, California.
They come from the same place where all of them except Synyster Gates comes from the same school, namely Huntington Beach High School. They formed in early 1999 in which personnel initially had only four people are M. Shadows, Zacky Vengeance, The Rev and Justin Sane (Bass).
Avenged Sevenfold's name is taken from one of the stories in the Bible. Although it takes its name from the Bible, M. Shadows admits that his band was not particularly religious nor aims to spread a religion or political belief to the fans.
On his way, Avenged Sevenfold had changed the flow of metal-core becomes more toward alternative metal. Rumor says this is because the vocalist, M. Shadows had to undergo surgery due to his vocal cords are torn due to scream too loud at a concert. But in every interview opportunity, Avenged Sevenfold often deny the truth of this rumor. Changes in the flow that they do more because they so enjoyed doing experimental in music and want an evolution in their musical style and flow.
