WA were founded by Paolo Palazzoli and Roberto Cosimi in 1997 and began to write songs together making in 1998 a world-music production with Africans musicians ( Gabin Dabiré ) entitled Zokué Kpolé (Forrest Hill Records), (under the art- direction of their great friend Paolo Panigada - Feyez - Elio e Le Storie Tese ) in wich there are three very representative compositions of the first WA sound: Egg, Vuela Libre and Three Ages In One.

In 1999 there was a tour of Zoquè Kpolé in many festivals in Italy and in Capoverde Islands ( Africa).

In 1998 during the making of Zokué Kpolé Palazzoli and Cosimi became friends of Massimo Dedo who taked part at some records sessions .

Since 2000 the three musicians began to work together towards a way of composing in wich their voices, the trombone, the electric bass and the piano gave them the chance to explore new dimensions of sound.

The Wa until 2004 played in many theatres and music-clubs in Italy and having get good successes in their shows, the three musicians realized that the right thing to do was to conceive a new work: Atmomy.

So, in 2006 the band arrived at a kind of composing and performing wich represents a pure example of world-jazz.
