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.
