The two musicians met in 1996 at one of Butch Morris's conductions and first played together, as a duo, in 1999. They have also played in a quartet with Gunter Muller and Jacques Widmer as well as with the group Chamaeleo Vulgaris, and they have appeared at the Visages des Nouvelles Musiques Suisses Festival in Marseille. These recordings are from 2001. “The playing of these two vital Swiss adventurers takes place in the wake of European research into improvisation over the last twenty years. Their duo playing reveals, beyond their qualities as instrumentalists, an understanding of how to position themselves, how to decode, and when to communicate and when not to communicate instantaneously. Uniting through a fine attentiveness to the other, and forming a unit that is thick, fleshy and powerful, but always alert, they let themselves be guided by the flow they create by provoking the instant reactions out of which are born many changes of atmosphere, tone, theme, and dynamic."-Theo Jarrier, Peace Warriors.
