Tony Harrington's blues guitar playing landed him work with Ginger Baker, Albert Collins, John Lee Hooker and more. But Harrington has long been enraptured by reggae and dub.

Upon returning to the States in the early '90s after a decade in Italy, Harrington settled in Columbus because of its thriving reggae scene and began touring with a group called Rasbongi. He eventually started churning out dub records under his nickname Doctah X.

Harrington's latest, "Agent from Kabul," was conceived as the soundtrack to an imaginary film by the same name that tracks a CIA agent/heroin dealer. Heavy bass, globetrotting percussion and hazy desert samples dominate. It's easy to get locked into these grooves.

Doctah X and video collaborator Plan 9 will appear alongside nine other acts at the Secret Song Records summer kickoff show Friday.
