Christian Kobi is one of the leading names on the improvisation scene in Bern, Switzerland. His work includes collaborations with Phill Niblock, Jurg Frey, Taku Sugimoto and Keith Rowe. His album 'Cathedral' closes a trilogy for saxophone solo that started with 'Canto' (2010) and 'r a w l i n e s' (2013). 'Cathedral' is an extensive piece that is built from the articulation of discrete blocks of sounds, as they amplify a range of microtextures, feedbacks and mysterious extended techniques. Kobi uncovers a wide range of sounds, which he extracts from the instrument in a singular sonic monologue, making 'Cathedral' a radical experience of listening.
