Kerrang! is a UK-based magazine devoted to rock music, currently published by Hamburg based Bauer Media Group. It was first published on 6 June 1981 as a one-off supplement in the Sounds newspaper. Named after the onomatopoeic word that derives from the sound made when playing a power chord on a distorted electric guitar, Kerrang! was initially devoted to the new wave of British heavy metal and the rise of hard rock acts. In the early 2000s it became the best-selling British music newspaper.
