This book is full of amazing facts! It doesn't matter where you open it, you will find something interesting and intriguing. For example, George Butterworth - I have long loved his "The Banks of Green Willow" without knowing anything about the composer. I learned that he died tragically young in the First World War, with his considerable musical potential unfulfilled.
Anyone who likes classical music will find plenty to interest them. Each of the 300 pieces comes with a recommended recording - very useful. The book has already introduced me to composers I did not know, as well as informing me about those I know and love. It is a beautifully produced book, with some lovely illustrations, and I thoroughly recommend it.
