Difficult times and political repression often inspire the most passionate art. Todos Tus Muertos emerged in the mid-1980s from the ashes of Argentina’s aptly named Dirty War — their name (which means “All Your Dead”) refers to the thousands of people killed by the country’s military and right-wing death squads. Not surprisingly, the Buenos Aires musicians are fiery and idealistic, hammering out their anthemic messages of revolution and social justice via an uptempo combination of punk rock, reggae and hip-hop. Vocalists Fidel Nadal and Pablo Molina have worked with such simpatico rock en español allies as Manu Chao, Tijuana No! and Negu Gorriak’s Fermín Muguruza. Arizona’s Fayuca also celebrate their Latino identity with a mix of hardcore punk and dub reggae, whereas L.A.’s uplifting Quinto Sol are primarily a roots-reggae band. The same bill is at the Echoplex on Tuesday, Nov. 22.
