Via their passionate, defiant storytelling, Los Tigres del Norte have been shattering borders since the ‘60s counterculture movement. In these courageous corrido rarities, the group show solidarity with immigrants in America. Their towering falsettos add poignancy with detailed, heartfelt imagery while they interrogate civil liberties (“Mis Dos Patrias,” “El Mojado Acaudalado”) backed by vigorous tambora rhythms and spellbinding accordion riffs.
