09 Ikeda, Ryoji. +/- (1996)
Original Format: Audio CD. +/- Touch Records. TO#30. <A high frequency sound is used that the listener becomes aware of only upon its disappearance.> Reboot. Shifting from form to content, from space to voice. Ikeda’s title track comes from the album with the liner notes that claim: “the listener can experience a particular difference between speaker playback and headphone listening.” Listening to this track on headphones, Ikeda focus on the second sound Johan Cage famously discovered when sitting in an anechoic chamber. Continuum referenced the eternal sound of the heartbeat, while +/- taps into the high pitched buzz of the central nervous system. Does Ikeda’s high frequency disappear because it slides into the bodies CNS frequency, or is it simply on the threshold of hearing? #
