Calderón, the year 2006 began her career as actress in the infantile miniseries of TVN called Karkú. The series was released on February 5, 2007, and lasted some months.
As almost all the infantile and pre-teen series on the Chilean television, Karkú also created a musical group, with the series' actors as members. The group was called Six Pack. Finally, they recorded a disc, that was released in 2007. In spite of the fact that the group did not have a main vocalist, Calderón made herself the main member attracting most attention, probably because she was relatively better known than the others.
