From 1958 to 1962 he studied music education at the Hochschule für Musik und Theater München and subsequently composition with Franz Xaver Lehner and Günter Bialas.
He pursued his education further with Josef Anton Riedl, Karlheinz Stockhausen and, above all, with Luigi Nono.
[2] His treatment of musical material was most strongly formed by his contact with Stockhausen, while Nono inspired in him an acute historical and political (Marxist) awareness, particularly evident in his second compositional phase, beginning around 1969.
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.
Nono encouraged Huber to seek a more thorough-going means of eradicating tonality, through a study of psychology in order better to understand human responses.
