After beginning his career in heavy metal bands Snake Eyes[1] and Thorn,[2] he was invited to sing the Brazilian Portuguese version of the opening of Saint Seiya: The Lost Canvas, which led him to shift his career focus to the production of anime songs in Brazil.

[3][4] Since then, he has been touring all over Brazil singing Brazilian Portuguese versions of other anime to which he was invited, such as Dragon Ball Kai and Saint Seiya Omega.

Rossi, with Japanese singer Yama-B (former vocalist of Galneryus), recorded a version of Hironobu Kageyama's Soldier Dream, the second opening of Saint Seiya.

[10][11] In 2017, Rossi returned to his heavy metal roots with the album Rec/All, produced by Renato Tribuzy (who also played in it), and special participations by Kiko Loureiro, Roy Z, Edu Ardanuy, Davis Ramay, Marcelo Barbosa, Felipe Andreoli, Marcelo Moreira, Pedro Tinello and Alessandro Del Vecchio.

[20][21] He also started a career as a voice actor, having worked on the Brazilian adaptation of animes like Sakamichi no Apollon (Kids on the Slope), Kanojo mo Kanojo (Girlfriend, Girlfriend)[22] and Maou Gakuin no Futekigousha (The Misfit of Demon King Academy).
