Don't be put off by the stupid cover, this book is a wealth of information. Written by someone who works in the business rather than a university grad, it doesn't tell you how to write a musical; if you don't know how to do that, then you shouldn't be reading this book. It lets you know where you will slip up, how to improve your work, how to avoid doing what everyone else always does at the outset. It covers every field from music and lyrics to marketing and production. If you think that you don't need to know about all these fields, believe me, you do. Along with a healthy slating of various successful but poor musicals, this book is a fantastic guide which you can read in a day. You will learn so much.
