Query: Solid Beethoven Biography

Lockwood's Beethoven gives an excellent overview of the great composer's art, life and times. If one wants a bit more of a psychological profile, Maynard Solomon's biography is my favorite. Thayer's Life of Beethoven is a more stolid volume, but it also has much more detail about smaller events in the composer's life.
