“Matias Tango” is the instrumental tango theme composed by Dorian Dionisi for Before We Forget, the feature film by Juan Pablo Di Pace and Andrés Pepe Estrada. Recorded by the Di Pasquale Orchestra of Buenos Aires for the film’s soundtrack, it is the core musical motif that returns at key moments throughout the story. The song “Ya no volaré” was later developed from this same tango theme.
