I've been pursuing Mozart's music lately, especially his music for wind instruments. Charles Rosen directed me to Hermann Albert's massive 1515 page biography, W. A. Mozart. I bought my copy a few years ago at a great price. Today for $29.00 plus $3.99 for shipping it can be yours.
There are two problems for me. (1) I hurt my left wrist by frequently grabbing onto Cook & Morton's 1725 page The Penguin Guide to Jazz on CD. (2) Charles Rosen had a photographic memory; something I haven't got!
I shall press on though. I'll let you know about my wrist and memory.
