Listen Only After World Doesn't End

Jamie's sailing off the edge of the world before the ball drops, so here's an advanced musical surprise.  However: Do Not Tune In Before December 22, 2012.  I'm serious.  This is one present you can't open early; you'll jinx it, and then where will we be? Flailing about the universe without a post-apocalypic music bed.  Come December 23, here's a sublime Sonic Byways for those who wait.
