Former percussionist of the Grateful Dead uses EEG brainwaves to control his concerts.

Instead of entrusting the light show to a technician, former percussionist for the Grateful Dead, Mickey Hart, makes sure that he is the one in control. What makes this more than a story about a control freak, is that he controls the lights using his brainwaves.

Hart dons a black cap studded with electrodes that pulls EEG data from his brain, these in turn, drive the light show at his concerts. Images of the musician’s brain also soar 40 feet in the air and change color to reflect different types of brain waves detected by the EEG.


Hart was led to brain science because of his grandmother’s dementia. For years, she didn’t seem to recognize him and largely stopped speaking, that is unless he played his drum for her, something which elicited her to say his name.
