Metal at 40
Emily Booth tells the story of the loudest and darkest form of rock. Heavy metal began in Britain in 1968, pioneered by such exponents as Led Zeppelin, Black Sabbath and Deep Purple. Each had their own unique sound, but shared an approach that embraced loud guitar riffs, powerful lead vocals and thunderous percussion. Since then, the music has flourished and diversified, spawning sub-genres such as grindcore, thrash and death metal, ever eager to embrace extreme subject matter.
