Hans-Werner Henze is an important composer of the 20th century. His elegant, neo-classic works comprise 10 symphonies and several operas such as "König Hirsch" and "The English Cat".
Henze created for Rosenthal the artist plate No. 9 "Der junge Lord" in 1975. For the opening of the entrance hall of the Castle Erkersreuth, re-designed by Ferdinand Ris, Henze composed a piece of music, performed by the Japanese percussionist Stomo Jameshita and his band.
