Brothers Porfirio and Candelario Delgado-Flores moved from Mexico to Los Angeles in 1947 and brought with them a burgeoning music business that specialized in custom guitar making. The store’s clientele includes famous artists like José Feliciano, but it’s also a source of community pride, giving back to Boyle Heights in many ways, including the creation of a 501c(3) nonprofit that provides free music lessons to local youth.
