Not just one of Mexico's greatest rock bands ever but one of the great rock bands of the '90s period, Caifanes kicked open the door for homegrown rock when their muscled-up 1988 remake of a traditional cumbia tune rewrote Mexican radio's rulebook. From there they fashioned a brutal but beautiful style of art-rock immersed in King Crimson, gothic, and New Wave. Saúl Hernández's singing bridged Robert Plant and Robert Smith, but with Latin and Middle Eastern frills, while Alejandro Marcovich's guitar reimagined Argentine folk music as lush prog rock. No rock en español since has matched it. And now “Heridos” is the group's first new song in 25 years. “It's about the people who are hurt in everyday Mexican life,” they tell Apple Music. “It's about the need to survive in an environment that is violent and marginalizes young people. It's the story about the many young people, both men and women, who are searching for their place in life.”
