 Huber took part in Stockhausen's composition project "Ensemble" at the 1967 Darmstädter Ferienkurse, an experience that gave him an appreciation of the potential for improvisation—a factor that marks not only his compositions for conventional forces, but also his mixed- and multi-media experiments.Stockhausen's influence can also be seen in Huber's exploitation of space and the incorporation of extraneous elements, such as vocal utterances in instrumental music, as a means of heightening expression.His period of study with Luigi Nono in 1967–68 was even more influential on Huber.
