Copenhagen Electronic Orchestraâs site is now full of sound and video. Our ensemble is an experimental electronic group which plays on circuit-bent toys as instruments. We donât use any traditional electronic instruments or computers. Besides the circuit-bent instruments only a few pieces of hardware (mixers, delay, compressor) are used. CEO was founded at an AUX workshop and you can hear all of us on the first few tracks. Now the hardcore remain and continue to bend and play.
