Original: Pieces from the late 1960s take up these techniques and tend towards experimental and a violent character - these include Revelation and Fall ( based on a poem by Georg Trakl ) , the music theatre pieces Eight Songs for a Mad King and Vesalii Icones , and the opera Taverner .
Simplified: Pieces from the late 1960s combine these ideas with expressionism and a violent character , for example Eight Songs for a Mad King which is about King George III .
