From the playful 'Sending It Down' to the intimate 'Ishin - Denshin' to the gobsmacking 'Con-Centration' (my personal favorite), each routine has been well thought out and choreographed to provide a highly entertaining and mystifying experience that will leave audiences stunned. This is a must for every mentalism bookshelf."
