“Bartmann Grunau” is the duo of Herbert Bartmann (double-reeds: chromatic bombarde—an ancestor of the oboe—plus bagpipes and whistles) and Christoffer Grunau (loops, synthesizers, FX).

If you wanted to classify their music stylistically, you could place it in a coordinate system whose axes are labeled Real-Time Music, Electronic Music, Improvised Music, and Ambient.
