In May 1872 he was in the quartet of soloists (with
Johanna Jachmann-Wagner,
Marie Lehmann and
Franz Betz) in the inaugural performance of
Beethoven's
Ninth Symphony at the foundation-stone laying of the
Bayreuth Festspielhaus, and the gigantic Niemann made a truly heroic impression when striking the foundation-stone with a hammer. By 1874, Wagner had mentally settled on Niemann for the role of Siegmund in the complete
Ring cycle as it was to be performed at Bayreuth. Wagner had involved Niemann in his discussions about the casting of the
Ring, but Niemann (who had agreed to participate without remuneration), in dudgeon because Wagner wanted a younger man for the role of Siegfried, arrived at
Wahnfried in 1875 for rehearsals and within three days had stormed out and injected poison into the atmosphere of exhilaration at Bayreuth. However, his departure gave Wagner the opportunity to coach
Georg Unger as Siegfried. Niemann returned to continue work in October, and in the following March he performed
Tristan under Wagner's supervision in Berlin. Rehearsals were resumed in May (with a new Sieglinde), and the opening of Bayreuth was brought to completion in August 1876. Niemann sang Siegmund with
Josephine Schefsky as Sieglinde and
Amalie Materna as Brünnhilde.
Lilli Lehmann wrote of him, 'never since have I heard or seen a Siegmund to compare with him... His intellectual power, his physical impressiveness, his incomparable expression were superb beyond words.' (Of his
Tristan she remarked, 'it was certainly the most sublime thing that has ever been achieved in the sphere of music drama.')
Saint-Saëns, however, considered that since the Paris 1861
Tannhäuser, time had eaten away Niemann's high notes, and he could no longer sing
piano or
legato. ==Later premieres==
