Query: A Must for Musicians!

I would highly recommend this book for any serious musician who wishes to delve into the relatively unknown realm of twentieth-century piano music. David Burge provides a thorough and interesting read full of fascinating bits of information and historical context. The accompanying cd is a special bonus. Occasionally the writing turns very opinionated or biased, however this is a small distraction in an otherwise excellent resource.
