Welcome to the Jungle was released in 1987 as the opening track on Guns N Roses' debut album, Appetite for Destruction, and quickly became one of the band's signature songs. Its aggressive guitar intro and streetwise lyrics about Los Angeles helped define late-1980s hard rock, and the track has since appeared in films, sports broadcasts and video games. On social media and soundboards, the instantly recognisable riff is now shorthand for danger, excitement and a chaotic welcome, keeping the song in regular use decades after its release.
