Josef Anton Riedl (*1929): Glas-Spiele, for an array of glass tubes (estratto) (1974/1977).
Performers: Lorenzo Ferrero, Stefan Gabanyi, Johannes Göhl, Michael Hirsch, Robyn Schulkowsky, Florian Tielebier-Langenscheidt. Gruppo diretto da Josef Anton Riedl.
The “Glas-Spiele” were sketched in 1974 and composed in 1977 in two versions. Along with “Metallophonic Raum – Klangwerkstatt” (Metallophonic Space – Sound Workshop, 1974), this is one of Riedl’s pieces for self-constructed instruments. Here the instruments are as unconventional as the manner of performance: they are made entirely of glass.
