The Italian composer Antonio Pileggi describes the work of this artist as follows: "His music is an original synthesis of the great occidental traditions and of an association of techniques derived from specific mathematical and geometric structures.

Atempo offers a space for the confrontation of thought as well as serious discourse from diverse points of view related to musical creation and interpretation.

Yearly, his compositions are heard in the most important musical centers of the moment: Paris, London Zurich, Venice, New York Montreal, Cincinnati Caracas and others.

Additionally, yearly performances of commissioned works are presented by the most prestigious musical institutions (Radio France, I'EIC, Aleph...) thus confirming his growing international recognition.

In other words, not only has he the temerity to explore structure and language to its limits but also is able to produce an astonishing result of great musical coherence and original timbres without ever breaking the balance between abstraction and human perceptual ability.

In the contemporary music scene of recent years, the works of Maestro Rivas are in the forefront of living Latin American composers.

He is considered the Venezuelan composer par excellence with great success representing his homeland of Venezuela, so rich in art and cultural personalities.

Nevertheless, in Europe and America we also recognize Rivas for his work as Artistic Director and the important pedagogic aspect developed by the Venezuelan and French Festival Atempo.
