Whenever you get the chance to hear the dazzlingly perfect Andras Schiff, whose delicate touch, technical wizardry and otherworldly tone are enough to give you goose bumps, don’t pass it up. The Hungarian-born British pianist has, in the past, been known for his superb take on Bach, succeeding — some say surpassing — the late Glenn Gould as the reigning interpreter of the monumental Goldberg Variations. He’s also garnered awards for his interpretations of Schubert, Schumann and Bartók. In the last few years, however, Schiff has taken on the daunting challenge that only the hardy few of the keyboard world dare to attempt: the complete Beethoven Piano Sonata cycle, each a masterwork with its own unique personality, reflecting Beethoven’s musical, emotional and spiritual journey from youth to older age. In 2004, Schiff began his Beethoven Sonata Project, an exploration of the 32 works in chronological order. (Interesting, isn’t it, that the Goldberg Variations also number 32?) He continues the cycle this week with the three Op. 31 sonatas and the incredibly demanding but oh, so glorious “Waldstein.” Walt Disney Concert Hall, ; Wed., Oct. 15, 8 p.m.; $36-$92.
