Hetz (2007)
audiovisual composition for piano
by Andreas Weixler (audio composition) and Se-Lien Chuang (visual composition)

Hetz is a result of a work in progress so far. Originally a piano, a viola and a clarinet performed an algorithmic score of an instrumental composition, genereated in Max. Its structures and sounds are then processed to electronic sounds on a computer using Pro-Tools and Plugins (Sci-fi and others) at the Sheffield University Sound Studio/UK. The structures of the piano part are played live again together with an visual flow of pictures generated in Max/MSP/Jitter.

produced 2007 at Atelier Avant Austria
premiered by the Juilliard Electric Ensemble

"Hetz" is a German word, which especially in Austria has a double meaning:
1. Hetz´ in the meaning of Hetze is a rush, 2. Hetz is to have very big fun.
In that it respresents the way we have been creating this piece of art: under big time pressure and with a lot of joy to hear and see it.
