Masaki Batoh — formerly of the Japanese experimental rock band Ghost — has recorded an album using a "brain pulse machine" (BPM) that translates brain waves into weirdly haunting and disturbing tones.
Wired's Angela Watercutter describes the device:
The unusual musical instrument, which [Batoh] had developed and built by a company called MKC, consists of... strange-looking headgear and a motherboard [pictured below is Batoh wearing the full set up]. Brain waves are picked up from the parietal and frontal lobes, then sent by radio waves to the motherboard, which converts the radio waves into a wave pulse that is output as sound.
The BPM Machine's bizarre goggles have indicator lamps synchronized with the motherboard so the performer can see their brain's musical output. Batoh said it takes practice to learn how to control one's mind in a way that produces a pleasing sound.
Batoh's album, which is titled Brain Pulse Music, features two tracks recorded using the bizarre instrument. Of the two, says Brainiac's Josh Rothman, the best track is called "Eye Tracking Test," which Batoh recorded by having a friend wear the BPM headset while he showed her a series of photos taken after last year's devastating earthquake in Japan. The video you see up top mixes clips from "Eye Tracking Test" with images like the ones presented to Batoh's friend; what you hear are her brain's reaction to images of the disaster.
More details about the brain pulse machine can be found in this instructional video (you can even purchase the device for yourself). All proceeds made from the album and the device go to the Japanese Red Cross. [Wired + Brainiac via It's Okay to be Smart]
