If you have an interest in classical music, then the name Otto Klemperer will be well known to you. Here is a beautifully presented two volume biography, very much a labour of love on the part of the author. A great read, and I particularly like having the notes at the foot of the page, not in an appendix.

Both volumes can be bought separately, but together come in a handsome slipcase.

I have read many biographies of famous conductors, and this ranks alongside Richard Osborne's book on Herbert von Karajan, and (best of all) Michael Kennedy's masterly and moving 'Barbirolli, Conductor Laureate', which I fear may be out of print.
