Beethoven is the subject of this rare Kempff video from the rich archives of the Canadian Broadcasting Corporation’s French network. The great “Hammerklavier” Sonata (Op. 106) is here given a truly magisterial performance in which the astonishing complexities of this great work are elucidated in the hands of a supreme Beethoven interpreter. The G Major Rondo, on the other hand, played with elegant simplicity, aptly demonstrates the adage that less is often considerably more.
