“I contacted Will Oldham to ask if I could use one of his songs in a film I was making,” begins film-maker Caveh Zahedi, “and he agreed for $500.

“A few weeks later, I wrote to him asking if he would be willing to take hallucinogenic mushrooms together for a would-be television series.

“To my surprise, he agreed.”

Director Zahedi’s introduction on this trailer for that “would-be television series” pretty much explains what’s going on here – he and Will Oldham, AKA Bonnie ‘Prince’ Billy, join for a psilocybin sesh and are alternately happy, (00:45), confused, (00:49), deep, (01:01), transcending, (01:07) and tired, (01:08).

Stupendous stuff - a new Bonnie 'Prince' Billy album, Lie Down in the Light, was announced here yesterday.
