Following a collaboration in the multidisciplinary improvisation collective In Sit-U in 2003, the two saxophone players Artur Vidal and Sébastien Branche decided to examine together the different relations that could be found between the way they play music and the other forms of expressions involving 'instant' composition.
Long tones, circular breathing, multiphonics, objects, are some recurring elements always renewed in a dialog between an idiom that settles through practice, and the necessity to improvise to create a music that takes into account each sound and each instant in its composition.
