This document provides research on the music magazine Kerrang! as a guide for a school magazine project. It discusses Kerrang!'s history of publication since 1981, focusing originally on heavy metal and hard rock bands. In the 1980s-90s it featured thrash and glam metal acts but later shifted to grunge bands. It began heavily featuring metalcore but this change alienated some readers who complained about the increased focus on emo and metalcore music. Examples of Kerrang!'s covers and contents pages are also presented.
