The last book of the New Testament has inspired countless narratives and cultural productions. In the realm of popular music the Apocalypse was embraced as synonymous of imminent catastrophe, generating a dystopian discourse.

This paper has two parts: first a conceptual review of the state of the questions and debate involved
and second, an exposition of selected songs, followed by a summary of their main traits.
