The Double Trio Live concerts are the result of the encounter between jazz musician Bruno Vansina and contemporary dancer and choreographer Salva Sanchis. In this ongoing collaboration project, where the live performances are the place where the research occurs, dance and music share the stage on equal terms. The premise for the performance is very simple: a jazz concert with three musicians and three dancers. The repertory, which combines jazz standards with compositions by Bruno Vansina, changes from concert to concert. The Double Concerts project was born from a will of exploring a very concrete approach to the relation between improvised dance and improvised music, and to do so in front of an audience rather than on a studio situation. In jazz music, improvisation is something that, although limitless in its possibilities, is framed within very precise parameters of time and harmony. Those parameters are not only tools to challenge and guide the improvisational skills of the soloist, they are also the context in which communication between the musicians is made possible. In this project, that context is used by the dance in order to organize improvisation in time and space, as well as the interaction between dancers; everything that happens in the dance is in direct relation to the (internal structure of the) music. Thus, the songs are the core of the concert, and both dancers and musicians use those songs to improvise. In other words, all six performers know what is going to be played, but none of them knows how it is going to be played; it is not a jam session, it's a concert.
