This piece is a sound installation co-commissioned by the Rhizome.org and Ramapo College. “Sonic City Lagos” is a multi-channel sound art work based on the major pathways of the city of Lagos. The artists collected samples of industrial sounds, conversations with people in the city of Lagos, and the acoustics of the city’s architecture. The installation makes use of flat panel ultrasonic speakers that project a narrowly focused and extremely unidirectional beam of sound. These speakers, placed at key nodes in the room, pan around the room driven by a computer-controlled system..
