Mentalism & Bizarre has always peaked my interest but I always felt that it takes a great deal of time and experience to build up to that kind of performance. Understanding how to read and perform for a crowd. Are there any resources you would recommend for someone starting out that wants to build towards this kind of performance?
I tell everyone to start off with the foundation tools & skills allied with traditional magic before attempting Mentalism and to some degree, Bizarre in that both of these areas are very performance oriented; the methods are typically super simple but the effect as well as the affect it has is entirely different from what we do with traditional magic. To my mind and that of my mentors in the past, having that foundation is paramount to one's success.
I worked with big illusions for most of the first 15+ years I was involved with magic in that I thought that was the right direction to head at the time. It still amazes me however, how many big box performers don't know squat about the basics of magic and I'm seeing this same trend with everyone that's learned to spell MENTALISM and then think themselves a "Mentalist". . . they simply haven't caught on to why the basics are important and end up having to back track at some point.
My (still free) resource book on Mentalism is something you may want to take time to peruse in that it will show you the different divisions or kinds of Mental performance that exist as well as the contrasting schools of thought, of which there are now 3 very distinct "traditions", one being less than a decade old at this point but it has made a very definite imprint on the craft, one that is not necessarily for the betterment or advancement of the craft. You can find said book through the link above.
Best of luck!
