I am really glad i got this DVD after buyiny the book it really help me to see more clearly what she was explaining in the book. i needed to know how to exercise and train my voice without damaging it,maintain a healthy voice,breath control, singing from my stomach without straining my neck muscles and the basic start up exercises i could use for my warm up and teach my fellow choir members by showing a demonstration by a PRO.she is really a PRO on this topic (i have tried others, i know what i am talking about)i believe this is one of the very best materials available in the market.she goes straight to the heart of what you need to know and this works very well for me. i would buy any other product she put out anyday. i aready have all 3 of her materials thanks to Amazon.com
