Fans of heavy metal music have created their own subculture that encompasses more than just appreciation of the style of music. Fans affirm their membership in the subculture or scene by attending metal concerts, buying albums, growing their hair long in most to (almost) all cases, wearing jackets or vests often made of denim and adorned with band patches and often studs, and since the early 1980s, by contributing to metal publications.

Air guitar is generally used in the imaginary simulation of loud electric or acoustic guitar music.

Brütal Legend is an action-adventure video game with real-time strategy game elements created by Double Fine and published by Electronic Arts for the PlayStation 3 and Xbox 360. The game was released during October 2009 in North America, Europe, and Australia. Though Brütal Legend was originally to be published by Vivendi Games prior to its merger with Activision, Activision dropped the game from its portfolio after the merger. It was later picked up by Electronic Arts, though Activision and Double Fine brought counter-lawsuits against each other over publishing issues. The issues were settled out of court. Later, Double Fine announced a port of the game for Microsoft Windows via Steam, which was released in February 2013. Mac OS X and Linux versions of the game were made available as part of the Humble Bundle in May 2013. A physical collector's edition for Windows, Mac OS X, and Linux was released by IndieBox in October 2014.
