The original band combining musicians of different nationalities (Brazil, Italy, India and Japan) - is the brainchild of Carlos da Costa Coelho. He aims to spread a repertory which is the result of a deep search for timbres and sounds by means of traditional and autochthonous instruments.

It is hard to define Coelho's music in one single genre. It is the result of his experiences in America, Europe and Asia. That is why it fuses different styles ranging from the classical one to the ethnic one, from contemporary music to jazz.

It is the point of contact for musicians coming from different artistic experiences. A concert of Oneness is like a musical journey to various countries through styles such as jazz, Brazilian music, Bengali folk and some oriental stylistic forms, translated into a Neo Humanistic language.

The versatility of Oneness has enabled the band to perform in numerous theatres, halls, churches and squares, in different festivals and venues like the Euromeet Jazz Festival, Musiche dal Mondo (Messina), The International Peace Festival (Assisi) and others, as well as touring in Italy, Germany and France. Their music has been chosen by film directors and choreographers and their pieces are often broadcast on different radio stations around the world (Israel, Austria, Brazil, Italy, Canada etc).

Apart from Oneness projects, the musicians of the group continue their careers performing and recording both as soloists and with prestigious names in the jazz, classical, ethnic and pop fields such as Enrico Rava, Richard Galliano, John Surman, Chris Lawrence, Maria Pia de Vito, Paolino Dalla Porta, Franco D'Andrea, John Anthony Calabrese, Mario Brunello, Claudio Abbado, Pandit Panchanan Sardar, Jamal Huassini, Ornella Vanoni, Ivano Fossati and others.
