If cities were judged by their underground, Linz would be a metropolis. Since the late seventies, the music scene of the Austrian steel city has been unique in its spirit of innovation and its non-conformity. The documentary ES MUSS WAS GEBEN portrays the emergence and development of the scene over two decades. From punk to hip hop, from New Volksmusik to industrial, Linz proves to be a melting pot for the most diverse musical styles. A portrait of a city on the move, where not only the blast furnaces are hot.
