Osiel Armando Vázquez Pérez raps under the name Tornillo, Spanish for "screw," a nod to the tools he handled helping his mechanic father growing up in the Cactus neighborhood of Soledad de Graciano Sánchez, San Luis Potosí, Mexico. He built his sound on cumbia rhythms and accordion lines instead of the usual boom-bap beat, a mix that owes something to Cypress Hill and to his mentor Santa Fe Klan.
He started out with the production crew Boom Bap Films before joining Santa Fe Klan's label, 473 Music, in 2021, opening shows for Santa Fe Klan along the way. His breakthrough single, "Un día todo se termina," pulled in millions of views on YouTube and put him on festival lineups outside San Luis Potosí. His albums "Cactus," named for the neighborhood he grew up in, and "Estilo fino" carry the same street-corner subject matter: migration, violence, nostalgia. He left 473 Music in 2025 to release music on his own.
