Los Crudos is an American hardcore punk band, prominent during the 1990s. Based out of Chicago, Illinois, all four members were Latino, so Los Crudos chose to sing almost all of their songs in Spanish. In addition, the band was extremely political; its leftist lyrics often commented on cultural and socio-economic difficulties inherent in the American way of life. Los Crudos incorporated DIY ethics into every aspect of the band including promoting and organizing shows, producing records, distribution, and so on.
