Pepe Garza was looking to revive a struggling radio station in Los Angeles. Looking for music, he took to the streets, and discovered a thriving scene, which he put on the air. Now, “Garza, a native of Monterrey, Mexico, has emerged as one of the most influential figures in the Latin music industry by giving L.A.’s immigrant population something it never had before — the chance to be on the radio and become stars. Until he moved here in 1998, the music of these working-class artists was dismissed as low-brow, crude or simply awful.”
