When speaking of complete recorded cycles of Beethoven's 32 Sonatas, the names of certain pianists are inevitably mentioned: Schnabel, Brendel, Kempff, and more recently, Goode and Schiff. But there are many individual recordings of greatness - some part of a complete cycle, and some by pianists who never recorded the entire ouevre.
Below is a list I've put together containing recordings I believe deserve a spot in every Beethoven lover's collection. I’ve limited this to two recordings per work, although there are many others that I would also recommend. All the Kempff recordings are from his stereo cycle (I’ve only sampled the mono, but know the stereo well).
