Spanish singer Alberto Comesaña made a decision to turn into a rock star following realizing his passion for music was more powerful than his profession as an agricultural engineer. In 1983, he became a member of Pedro González, Luis García, Javier Martínez, and Gonzalo Gil in developing Semen Up, producing their debut in 1985 with Lo Estas Haciendo Bien. The group disbanded in 1989. After shifting to Madrid, Comesaña teamed up with vocalist Cristina del Valle inside a task known as Amistades Peligrosas, liberating Retratos de una Intriga in June 1991. The duet announced its separation in 1998. After registering to EMI Music Spain like a solo designer, Comesaña documented a Latin pop recording known as Perversiones that premiered in 2001.
