The session musicians Rodolfo Cava (singer) and Yulie Ruth (bass player) completed the line-up that recorded the demo.

The songs were "Chico callejero", "Rompe el hechizo", "Gente del sur" and "La bruja blanca".

They met the bass player Guillermo Sánchez with the help of Giardino's friend Sergio Berdichevsky, member of WC at that point.

It was a successful release, and in its wake the band appeared on the TV show Ritmo de la Noche and played in cumbia concert halls because typical rock venues could not accommodate their large audiences.

Later that year, they were invited to play in the Festival Monsters of Rock in São Paulo, Brazil, along with Ozzy Osbourne, Therapy?, and Alice Cooper.

The radio station La Mega aired frequently the old "Mujer amante" song, generating a renewed interest in the band.

[3] Rata Blanca played with famous member of Deep Purple Glenn Hughes as a guest at the Gran Rex Theater, in 2003.

In order to gain a more international profile, Giardino approached former Rainbow singer Doogie White to record an English version of the Forgotten Kingdom album in 2009.

In 2013, original members Gustavo Rowek, Sergio Berdichevsky and Saul Blanch reunited with Rata Blanca for some shows.
