The first great pianist to record all of Schoenberg's piano music was Glenn Gould, and if you grew up with Gould's interpretations, then you're in for a shock. In the first place, Pollini actually plays what Schoenberg wrote--Gould freely altered the text in ways that would have driven the composer insane. And then there's the humming--yes, believe it or not, Gould did manage to sing along as he played. Pollini's quieter, less vocal approach conveys much more of what Schoenberg actually wrote, with no sacrifice of expressiveness. And although most of the pieces on this disc are quite short, they are nonetheless important. It was in his piano works that Schoenberg worked out his theories of free atonality and 12-tone composition. So for anyone interested in these critical musical developments, this disc is essential listening. --David Hurwitz
