Peter's libretto for composer Norbert Zehm's cantata/song cycle SILENCE & POVERTY for choir, soloists and wind orchestra premiered in 1994 at the Stift Reichersberg monastery in Austria, conducted by Johann Mosenbichler.
In 1995 it toured the Italian cathedrals at Lana and Bruneck, where Hans Obkircher conducted.
The soloists for both productions were Maria Brojer, Claudius Muth and Arno Raunig.
Both productions were also recorded and broadcast on European radio.
Arno has worked with Peter and Norbert again recently, taking the title role of their opera Cadence Macbeth at Tiroler Landestheater, Innsbruck.
He currently includes a signature piece from the opera - The Year Is A Song - in his live concerts.
