for example Gottfried Huppertz (1887-1937)famous for the Metropolis fritz Lang masterpiece (1927,cd Capriccio C 5066),but also Die Nibelungen (F.Lang,1924) and the medieval tragedy "Zur Chronik von Grieshuus (Gerlach,1924),an astonishing forerunner to my so dear Korngold !
I am putting this thread on hold as there are existing threads on Huppertz.
