I heard Bronfman play Prokofiev Sonatas 4 and 6 last night, capped with Beethoven's Archduke, with Martin Beaver and Lynn Harrell. Bronfman is a magnificent pianist, able to wrest an enormous palette of sounds from the instrument. His technique is sovereign, and his ability to play lyric passages most evocative.
At several times during the sonatas, Mr. Bronfman, a great bear of a man, pounded the piano during fff passages with such severity members of the audience noticably jumped, myself (twenty rows back) included, our ears in pain. It sounded, and felt, as if Soviet tanks crushed us beneath their steel treads. I have no doubt this was the intended effect. These moments were often followed by sweet passages played with utmost tenderness (although the Steinway D had to be re-tuned for the Beethoven, a trio rendition that contained not a single harsh tone, yet was full of fire and verve.
Is there ever a justification to draw painful tones from the piano? Does Art require this? Or is pounding the piano, well, just pounding the piano?
