The publication of "Transmission Arts: Artists and Airwaves" (PAJ Publications, 2011) by Galen Joseph-Hunter, Penny Duff & Maria Papadomanolaki is officially here at this book launch with radio art performances. This work considers a new art genre, and "Transmission Arts: Artists & Airwaves" brings together a genealogy of 150 artists and artworks — and more than 250 images — from 1921 to the present that encompasses performance, video, radio theater, sound art, media installation, networked art, and acoustic ecology. This is an account of the ingenuity and creativity of artists who have made new discoveries in broadcast, public works, performance composition, sound, and text, stretching the boundaries of both transmitter and receiver. At a time when public access struggles with corporate control of the airwaves, artists have combined activism and communications technologies to represent alternative worlds on the electromagnetic spectrum. Reading and remarks from Galen Joseph-Hunter and Bonnie Marranca. Live performances from Maria Papadomanolaki, Matt Bua, and Tom Roe. Many of this project's authors and artists will be in attendance.
