ECHO allows you to transfer thoughts directly into the minds of your spectators — the effects below illustrate only some of the applications possible. It can also be used for dual reality, pre-show work, trance inductions, and more.
Two spectators are chosen. Spectator A thinks of a card, a song, a movie — anything. Without collusion or prompts, Spectator B slowly closes their eyes and covers their ears to block outside interference. Spectator A simply concentrates on what they thought of. It slowly appears in Spectator B's mind.
Borrow any spectator's phone and open their recording app. Start recording — you'll have a one-sided conversation, with no reply. When the recording is played back, the audience clearly hears a ghostly voice answering your questions.
An important part of how I approach mentalism is guiding the audience from a rational state of mind into a perceptual one — to make the moment feel as close to “real” as possible. ECHO isn't just an effect; it's a tool for strengthening the establishment of the “real.” New tools open new pathways in every art form. In magic and mentalism, they're the gateway between reality and illusion — catalysts for shaping the inner world of an audience. I believe ECHO is a breakthrough in the way I perform magic and mentalism. I hope it does the same for you.
