Los Auténticos Decadentes is an Argentine band formed in Buenos Aires in the mid-1980s, known for blending ska, rock, cumbia and Latin rhythms into a party-oriented sound. Over decades of activity they have become prominent in the Spanish-speaking rock and pop scene for their upbeat arrangements, use of brass instruments, call-and-response vocals and a theatrical, humorous stage presence. Their repertoire frequently mixes danceable grooves with satirical or celebratory lyrics, drawing on popular and folkloric styles as well as punk and ska influences. The group’s collaborative approach and emphasis on communal performance have been central to their public identity.
