Infrequency is an ongoing podcast series of live performance recordings and artist commissions, in conjunction with Tate’s Intermedia Art programme. The podcasts will be infrequent and intriguing, building on and developing a legacy of avant-garde and contemporary sound and electronic music. Current episodes include a performance recording of Tony Conrad (See current programme for further details). Previous event recordings are also available, including work by Christian Marclay, Alvin Lucier, John White, Achim Wollschied, Robert Henke (aka Monolake), Ryoichi Kurokawa, Sachiko M and Toshimaru Nakamura.
