Mexican teen pop sensation Kairo was formed in February of 1994 by Eduardo Verástegui, Jean Paul Forat Morales, and Francisco Carlos Zorrilla González. Soon the threesome issued their debut album, called Signo del Tiempo. After releasing 1995's Gaudium, 1997's Cara a Cara, and Libre, former Mister Mexico Gabriel (born Gabriel Soto Borja Díaz) replaced Eduardo Verástegui, who decided to concentrate on his acting career, later debuting as a solo artist. In 1998, ex-Tierra Cero Paulo (born Paulo César Quevedo de la Vega) took Jean Paul's place and Roberto (born Roberto Assad Martínez) replaced Francisco Zorrilla. That same year, Kairo's Pasiones was released.
