On this edition of Making Waves, Bekah Simms interviews John Oswald on his early analog work Vertical Time, his seminal plunderphonic work Dab and his large scale sound installation for the Crystal at the Royal Ontario Museum. This monthly program is produced by New Adventures in Sound Art (NAISA). The program features selections from the NAISA archives and is produced by Darren Copeland, NAISA Artistic Director. NAISA is a Toronto-based organization that presents performances and installations spanning the entire spectrum of electroacoustic and experimental sound art. The objectives of NAISA are to foster awareness and understanding locally, as well as nationally and internationally, in the cultural vitality of experimental sound art in its myriad forms of expression.
