He was an authentic forerunner of our popular music.

As time goes by, the value and quality of his work grow with indelible edges; the following are titles that speak for themselves: “El entrerriano” and “Don José María”.

Rosendo generally played as a soloist, and his income depended on the generosity of the attendants.

A violinist and a flutist joined him if the importance of the session made it necessary, the repertoire to be played was read on handwritten lead sheets because tangos at that period were not published.

His family was at a solid financial position, but when he was only three years old, he and his brother Sergio were orphaned by the death of their father.

During Rosendo's adolescence his financial resources allowed him to study piano at home.

We very often read commentaries about his body features: a gallant brunet with certain arrogance in his features. 

The lavishness with which he spent his money finally emptied his pocket. Fortunately, his musical knowledge made possible for him to teach piano at well-to-do homes. In such a way he earned his living for a time.
