Chairs of Fury is an excellent manuscript that outlines a simple - in a "why didn't I think of that?" sort of way - method with tons of applications beyond just the routines listed. The writing is clear and the specific routine with its variations are quite good. The ever present Chair Test is a tried and true mentalism demo, so many pros have developed and adapted the basic idea a few times over. Most play big and are suited for a medium to large audience. "Chairs of Fury" has removed the need for multiple participants and allows for a close-up and one-on-one performance. It incorporates a few known concepts and combines them quite capably, and the payoff, as is, has somewhat of a free will feel about it.
Again, I really like this release and will be performing it and derivatives of it from now on.
