We celebrate our 400th episode with a song we love. It's a standout for the original band in a number of fascinating ways, and has a cover that turns everything on its head to brilliant effect. Strange Currencies, originally by R.E.M., covered by Louisa Stancioff. 

Rich got the name wrong during the episode, but the outro music is Rumble by Link Wray. He was probably overcome by the reverb.
