The song follows the release of a documentary about the legendary artist.

The Upsetter: The Life and Music of Lee “Scratch” Perry is a documentary about Perry’s music and life, directed by Ethan Higbee and Adam Bhala Lough and narrated by Benicio Del Toro, and a free BitTorrent Bundle has been released to promote the film’s release.

The Bundle features exclusive artwork by Perry, behind-the-scene photos and — for the price of an email address — a never-before-heard Perry song produced by Clams Casino. Stream the gauzy ‘Jesus is a Soul Man’ below and grab the BitTorrent Bundle.
