Otto Klemperer's Beethoven is one of the towering achievements in the history of recordings. By today's standards, these performances are hopelessly old-fashioned: dark, heavy, and frequently very slow. But they are also the grandest, most unsentimental, most purposeful versions in the catalog.
Klemperer's Mozart recordings have been available almost without a break since their original LP releases. It's not hard to see why, since he conducted Mozart with authority, never lapsing into either heavy-handed Romanticism or its opposite, treating the music like a fragile piece of porcelain. Klemperer's sturdy rhythms make even some of his slow dance-based movements seem faster than they actually are. Period performance buffs will still feel this big-band Mozart is too heavy but the more open-minded will appreciate the way Klemperer brings the winds forward to create appropriate balances with the strings.
