“Mr. Sauer opened the concert with a vigorous performance of the Sonata No. 16 in G (Op. 31, No. 1), actually the latest work to be played, and the most rambunctious. Its chunky chordal opening and its exuberant finale show us a composer who draws his energy from at least the pretense of iconoclastic recklessness. But what, then, do we make of the gracefully ornamented Adagio grazioso? Mr. Sauer played it with an elegant formality that showed it for what it was: a feisty composer’s moment of good behavior between raucous pranks.”
