Three-part a cappella harmony finds itself slowly warmed by spare instrumentation. A bedraggled man, bobbing adrift on the ocean in a yellow inflatable life boat, regains consciousness. The first thing he sees is a black rock. There is no one else with him, no land nearby. He weakly tosses it overboard and closes his eyes for a moment.
When he opens them again, a small pile of rocks has gathered in front of him. After looking around, he starts tossing them out, turning his back briefly. When he turns back, the rock pile has grown so big that it's nearly pushing him out of the lifeboat.
