Wilhelm Kempff was the premier German pianist of the postwar period, so it's no surprise that he was considered one of the supreme interpreters of Beethoven. He recorded complete sets of the sonatas and concertos twice, and just about all the rest of the chamber music with piano as well. Kempff was a classicist by nature, and his approach to Beethoven was clear and poised rather than impulsive, but it was never lacking in sheer power or virtuosity when necessary. His last cycle of Beethoven sonatas is rightly regarded as his musical testament. Even if the mono recordings offered a few more exciting moments in a couple of works, you can't go wrong here--there isn't a dud in the lot. --David Hurwitz
