On his return from Brazil, Rowek agreed to help Walter Giardino recording a demo of some songs.

That would be temporary, however with the result obtained in the demo, and seeing that the project Horcas was delayed, together they founded the band Rata Blanca.

Nativo released four albums, but Rowek decided to end the band to devote himself to his personal project.

Parallel to Nativo, in 2006 were invited by singer Mario Ian, who had shared the stage in Rata Blanca composing together several tracks on the album "Entre el Cielo y el Infierno", to join his band as guest musicians, but before the success and impact obtained decide to form a project band with Ian.

In 2012, Gustavo Rowek leaves Ian due to focus his career in a new soloist project.
