Marcela met the Argentine guitar player Jorge Omar Sosa in Italy. Together they have created a repertory of Argentine folk music and tango.

Marcela and Jorge, besides their voice and guitar, also use Argentine folk instruments such as the bombo, water bowl, chas chas, the Peruvian cajon, creating a musical repertoire that goes from Zamba, Chacarera and Chamamè, to popular Argentine and South American songs, to the Argentine tango. They have performed at Milongas and tango clubs in Rome and its outskirts: Tangofficina, Caffettin de Roma, Roma Vintage, Mate de Luna, and others.
