The Carrier Frequency (Play, 1984)
From the Stan's Cafe website: "The Carrier Frequency, Impact Theatre's collaboration with the novelist Russell Hoban, was one of the Eighties' most outstanding and influential theatre shows. It is set in a post-nuclear world, where brutalised steel and concrete structures rise from a giant pool of water. It depicts six figures lost in an absurd and exhausting ritual, trying to revive a departed civilisation. Despite its harrowing subject matter, the show retains moments of ludicrous slapstick and verbal wit."
