Collaborators have to step up when they share tracks with the ranchera king. Alejandro Fernández makes a great case for inherited talent when he joins his dad—aka “Chente"—for a beautiful, dobro-tinged version of "Me Olvide de Vivir" (I Forgot to Live). Salsa queen Celia Cruz brings along Cuban percussion to their appropriately titled "Tu Voz" (Your Voice). And north meets south when Tony Bennett snags the mustached mariachi maestro for a bilingual "Return to Me” (Regresa a Mi).
