At the same time, Noel Schajris (from Argentina, now a nationalized Mexican) was preparing another solo album after making his debut in 1999.

The two wanted to sing, but Noel preferred the piano, and Leonel, the guitar, for which at no time there was collision of interests, but an integration of musical inclinations.

They later began to write and record their self-titled debut album Sin Bandera, which touched the feelings of the romantic public in a special way with the production of the fellow musician Aureo Baqueiro.

They both thought that we lived in a separate society, that we get to the point where we no longer believe in ideology or in language, and we end up thinking that one is the enemy of the other.

The duo wants to spread that message through the music; We are one and that feeling is the best route to communication; That love is the fundamental energy that gives sense to all.

"Entra En Mi Vida" ("Come Into My Life"), their first single, is a song written by themselves, in which they express the magic of love and the emotions that occur upon a first encounter with that special someone.

By the end of 2003, their second album De Viaje (Traveling) arrived, produced again by Baqueiro, that likewise approached the millions of sales at international level, little by little.

In 2004 they carried out their tour to Venezuela, Bolivia, Argentina, Paraguay, Chile, Ecuador, Colombia, Mexico, the United States and Spain, among other countries.

This time, Sin Bandera teamed up with noted producers Áureo Baqueiro, Mario Domm and Jay de la Cueva.

The CD also includes De Vita's philosophical "Un buen perdedor" ("A Good Loser"); Sanz's anthemic and Beatlesque "¿Lo Ves?"
