This thoughtful bass-baritone on the rise, who brings his nuanced Leporello to the Metropolitan Opera's "Don Giovanni" in February, puts early German Romanticism in perspective in a Carnegie Hall recital with the pianist Wolfram Rieger. The lieder of Mozart, Beethoven and Mendelssohn are all featured, but Schubert remains the star. The program mixes rarities with favorites, including Beethoven's "Adelaide" and Schubert's "Erlk�nig."
