This is a collaboration for "Lines of Sight" by philosopher and pioneer of mini-FM radio, Tetsuo Kogawa, and sound artist Yasunao Tone, based on an e-mail exchange about radio art. In "Lines of Sight," the artists Barbara Held and Pilar Subirá offer a very personal program to explore the extraordinary range of musical registers present on the world scene, following paths as diverse as musical notation and non-linear composition, and introducing artists who explore ideas of broadcasting as a means of creative expression for Museu d'Art Contemporani de Barcelona.
