[5][6] She has performed concerts in France, Italy, Spain, Portugal, Belgium, Germany, Switzerland, Holland, England, Morocco, Angola, Senegal, the United States, Peru, Ecuador, Puerto Rico, Venezuela, the Dominican Republic, Honduras, Uruguay, Colombia, Costa Rica, Guatemala, Panama, El Salvador, Argentina, Brazil and Mexico.

[11] She further developed her repertoire with traditional and rock music on the radio, and recalls singing in competitions at age seven, knowing 300 boleros by eight, and making records by nine.

She never used this education later in life, but she credits her university experience with exposing her to other people who were interested in art and left-wing politics, especially anti-war movements.

[12] In 1976, Libertad began to travel abroad, and was inspired by the musical traditions and political consciousness she encountered in the places she visited, such as Cuba.

During her career, Libertad shared the stage with other international artists such as Mercedes Sosa, Joan Manuel Serrat, Silvio Rodríguez, Pablo Milanés, Alberto Cortez, León Gieco, Juan Carlos Baglietto, Guadalupe Pineda, Chico Buarque, Gal Costa, Alfredo Zitarrosa, Cesária Évora, Vicente Fernández, Eugenia León, Juan Gabriel, Miguel Bosé, Plácido Domingo, Armando Manzanero, Simón Díaz, Willie Colón, Tito Puente, Oscar Chávez, Iván Lins, Riccardo Cocciante, Soledad Pastorutti, Marco Antonio Muñiz, Soledad Bravo, Amália Rodrigues, Susana Rinaldi, Phil Manzanera, Lucha Villa and the group Inti Illimani, among others.

[13] The Nobel Prize winning Portuguese author Jose Saramago writes of her work: "The first time I heard Tania Libertad sing, it was a revelation from on high - from a place where only a naked voice might go, alone in the world, unaccompanied by any instrument.

Tania was singing the Rafael Alberti composition "La Paloma" a capella, and each note touched a string in my soul until I was completely dazzled."

[9] Her appreciation of Afro-Antillan music has been reflected in works which reference Trova and Nueva canción, and have included arranged renditions of compositions by Silvio Rodriguez.
