Retaining his title as salsa’s most forceful voice, Canciones Que No Se Olvidan finds Tito Nieves still dominating a groove like no one else, even if these particular rhythms sway more than they snarl. He glides over “Lo Mejor de Tu Vida” and “Perdoname,” teasing you with flashes of his legendary power. And when he finally erupts on “Me Olvide de Vivir,” it’s the primal release you hoped would arrive, even if he delivers it via a gut-punching ballad.
