Welcome to the Jungle was released by Guns N' Roses in 1987 as the opening track of their debut album Appetite for Destruction, and it became one of the band's signature songs. Its aggressive guitar riff and streetwise attitude helped define late-1980s hard rock, and the song later appeared in films, adverts and video games, keeping it familiar to new audiences. Short clips of the intro now circulate widely as a shorthand for danger, swagger and high-stakes entrances.
