Otto Wiener was an Austrian baritone and bass-baritone, active in opera and concert repertory. He became associated with German and Austrian stage works during the mid-twentieth century.

In the Pristine catalogue he appears in Beethoven, Berg and Mahler, including Horenstein’s Beethoven Ninth, Häfner’s Lulu and Klemperer’s Mahler material.

Wiener’s singing brought firmness, clarity and theatrical definition to repertory ranging from modern opera to late-Romantic symphonic song.

His page is justified by repeated catalogue presence and career standing. Wiener gives the Austrian vocal shelf a dark, articulate baritone line.
