The Bing Selfish Radio Show: Selfish Tales

[Repeated from Monday 2pm.] Selfish Tales: Selfish in Space - Part 1. In a post-scarcity universe, an intrepid team of space explorers encounter (and epitomise) scarcity of good sense, good anticipation and good music when they stomp into the middle of a civil war between Experimentalists, Avant Gardists and Improvisers. Will they manage to make a bad situation worse? A deep philosophical meditation on the nature of art, interstellar navigation and reality, with jokes. Selfish Tales is the latest emanation from The Bing Selfish Radio Show and brings you stories you never knew you wanted to hear. Expect music, including in this case, experimentalism, avant gardism and improvisationalismisticality, plus actual songs, voices, sounds and surprises. We can't tell you much more right now, or you'd just steal all our ideas and do it all yourself with a finely tuned grant application.
