well as the rock–bolero sound of their first big hit, "Bolero Falaz" ("Talkative Bolero"). "At first what we were doing was very elementary", said Andrea. "But since we've played out a lot, learned to compose, and made a few records, even though we haven't had a lot of formal training in music, we've just learned how to develop. We've done it in a very instinctive way, but I think it's very valid." The hit song "Bolero Falaz" not only had a strong rock-ballad feel, but it showcased Andrea's powerfully seductive voice, one influenced by her mother, who sang boleros, rancheras, and tangos, and the great legends of nueva canción, Iike Joan Manuel Serrat, Mercedes Sosa, and Pablo Milanés. The song broke the band on MTV Latin America and made them stars all over Latin America.
