Fans of heavy metal music have created their own subculture which encompasses more than just appreciation of the style of music. Fans affirm their membership in the subculture or scene by attending metal concerts–an activity seen as central to the subculture, buying albums, in some cases growing their hair long, wearing leather jackets and t-shirts with band names and logos and most recently, by contributing to metal websites. Metal fans may also write or take photos for metal zines.
