Sentidos Opuestos was a Mexican pop duo formed by local producer Miguel Blasco in the early '90s. Alessandra Rosaldo started singing at the age of 12, soon becoming a backup singer for Latin star Lucero. Joined by Chacho Gaytán, the act released a self-titled debut album in 1993, getting their songs "Historias De Amor" and "Escribeme En El Cielo" climbing on local charts. A year later, Sentidos Opuestos recorded 'Al Sol Que Mas Calienta', moving to Barcelona
