“Hook a whole bunch of brains up to a computer, capture and play the sounds they make, and you get, well, not quite music, but certainly some interesting noise. That’s exactly what happened at the Cyborg Echoes Deconcert in Toronto over the weekend. The concert was billed as a participatory event, and it certainly was: Audience members’ brains were scanned, the scans were transformed into sounds, mixed with a solid little backbeat from some heart scans, combined and played back to create Music in the Key of EEG.”
