I have recently been examining "Patterns of the Hypnotic Techniques of Milton H. Erickson, M.D. Vol. I" by Richard Bandler and John Grinder. Its a GREAT book for anyone interested in suggestion, hypnosis, or the works of such performers as Derren Brown or Luke Jermay. The recent thread posted on the best magic books got me thinking off topic a bit and I figured I would ask the community about this. In your guys' opinion, what are some of the greatest works on staging, acting, body language, suggestion, hypnosis, etc?! ANYTHING that RELATES to our craft that has helped you or may help others...
