Buy the book from On Stage Success
I started out by attended one of Tom's speaking engagements and was really impressed at the impact of the makeovers of the bands who were present. While there is nothing quite like seeing this, his new book is a wonderful reference for all the material.
His material includes so many things that, once you hear and see them, your reaction is: "Well, that is obvious" except that you'd never think of them yourself. The result is that thay are easy to internalize and apply, albeit with practice to make them your own.
At the session I attended, I got talking to a booking agent at the mixer. He was there not to learn performance but to learn to see what would make people effective in the venues he was booking for. That he found the session highly instructive is telling and a clear message to performers who fail to hone their technical performance skills and their show's performance aspects.
Subsequently I've enjoyed the DVD set.
The book includes the material presented in Tom's speaking engagements and the DVDs in a thorough way that lets one reflect on the material. It is a great reference.
