His ideology involves deep Rastafarian culture from countries like Jamaica and Haiti; one of his inspirations, as with many reggae groups, is Bob Marley.

Influenced by reggae rhythms and the music of the Afro Argentine community, Nadal is best known for his work with Todos Tus Muertos.

In the last albums of Todos Tus Muertos and Lumumba, Fidel felt the need to play more reggae and leave the hard music behind, but when both projects disappeared, he decided to go on by himself.

The same year, he launched three albums, Selassie I Dios Todopoderoso, with much reggae and pure rasta-vibe lyrics, including a cover of Mexican group Los Tigres del Norte, Cuando gime la raza, and Cabeza negra, with numerous guest musicians (which gave more variety to the album and made it different from the first one).

Finally, Repatriación appeared, with a number of collaborators, and with another cover of a Tigres del Norte tune, La Puerta Negra.
