"Cellist Katinka Kleijn performed both halves of a duet Sunday night. Her hands played the cello, and her brain, hooked up to a headset that detects cerebral electrical signals, played itself. (...) "Intelligence in the Human Machine,” the cello/brain duet, explored the relationship a performer has to the music she’s playing. During the performance, at Chicago’s Cultural Center, Kleijn wore an Emotiv EPOC, a neuroheadset with 14 sensors that attach to the scalp and detect brainwaves. In front of her, a laptop flashed a word and a few measures of music. She then played the music on her cello, interpreting the word onscreen. At the same time, her brainwaves, translated to audio, changed sounds as she reacted to the word. (...) “Not only is Katinka playing the cello, but she is also, in a sense, playing her brain waves, emphasizing what’s going on in her brain while she’s performing,” Dehaan says." - Amira
