During their school years, the Lascurain sisters and some friends participated as a group in various music festivals, calling themselves "Las Jeans".
On 29 November 1984, the group signed a record deal with EMI and became Mexico's first all-female musical trio in thirty years.
The artistic director of EMI Capitol Mexico, Luis Moyano, renamed the group "Pandora" after the first woman created on Earth in Greek mythology.
Pandora peaked at number one in the Billboard Hot Latin Tracks in 1993 with their rendition of "Without You", titled "Desde el Día Que Te Fuiste", taken from their cover album Ilegal.
