Das siebte Kreuz
His later works, while less controversial, continued his political and social engagement. His "Requiem" (1990–93) comprised nine 'sacred concertos' for piano, trumpet and chamber orchestra, and was written in memory of Michael Vyner, the artistic director of the London Sinfonietta. The choral Ninth Symphony (1997), – "dedicated to the heroes and martyrs of German anti-fascism" – to a libretto by Hans-Ulrich Treichel based on motifs from the novel "The Seventh Cross" by Anna Seghers is a defiant rejection of Nazi barbarism, with which Henze himself lived as a child and teenager. His last success was the 2003 premiere of the opera "L'Upupa und der Triumph der Sohnesliebe" (English: The Hoopoe and the Triumph of Filial Love) at the Salzburg Festival, with a text he wrote himself, based on a Syrian fairy tale. Other late compositions include "Sebastian im Traum" (2004) for large orchestra and the opera "Phaedra" (2007).
