Hells Bells is the opening track on AC/DC's 1980 album Back in Black, the band's first record with singer Brian Johnson after the death of Bon Scott. The song begins with a tolling bell before the band's guitar riff takes over, and that stark opening helped make it one of the group's most recognisable songs. Over the decades it has become a staple for dramatic entrances in sports arenas, films and online edits, where its slow build still signals power and impending action.
