Tatiana's first major musical project was as the character Jane in the 1984 live stage performance,
Kuman, a Mexican
rock opera about a
Tarzan-like character. The show's 1984 album soundtrack also entitled
Kuman was released under the group name, Cristal y Acero ‒ the rock trio consisting of guitarist Icar Smith, bassist Carlos Ortega, and drummer Samuel Shapiro. IN 1986, Tatiana released a single and filmed a video, both titled
Cuando Estemos Juntos, with former
Menudo member, Puerto Rican singer
Johnny Lozada. The song was meant to create awareness among youth in Puerto Rico, Mexico and the rest of Latin America about the potential consequences of sex before marriage, including sexually transmitted diseases and pregnancy at an early age. From 1984 to 1994, Tatiana released 10
pop music albums which garnered numerous hits throughout Mexico and some parts of
Latin America. ==Career as children's entertainer ==
