Back in Black is the title track from AC/DC's 1980 album of the same name, the band's first record with singer Brian Johnson after the death of Bon Scott. Its opening riff, built around a driving electric guitar figure, became one of the most recognisable intros in hard rock and helped the album become one of the best-selling records of all time. Decades later, the short intro still circulates in edits, sports broadcasts and memes because it signals confidence instantly, even to listeners who do not know the full song.
