Karl Liebl (1915-2007) was a German tenor, active in opera and especially associated with Wagnerian repertory. He sang at major German houses and appeared at Bayreuth.

In the Pristine catalogue he appears in Leinsdorf’s Metropolitan Opera Das Rheingold with George London, Jerome Hines, Irene Dalis and Jean Madeira.

Liebl’s singing brought the bright dramatic tenor profile needed for Wagner roles that must cut through dense orchestral and ensemble textures.

His page is justified by career standing and catalogue context. Liebl gives the Met Ring shelf a clear German tenor edge.
