I seem to recall reading somewhere that Nashville is a guitar town, and if that’s true, this so-called revival — in a church, no less — should attract throngs of the six-string faithful. It’s a lineup of awe-inspiring musical mastery in an equally awe-inspiring setting, the Downtown Presbyterian Church’s fabulous Egyptian revival sanctuary. Michael Chapman may not be a household name, but the British fingerpicking visionary is a cult hero, and one of the most revered guitarists alive. Chapman came up in the late-’60s Cornish folk scene and recorded for the Harvest label, then home to Pink Floyd and Deep Purple. His album Fully Qualified Survivor, which also featured Mick Ronson, was John Peel’s favorite album of 1970. That alone would have been enough to ensure his legacy, but Chapman hasn’t rested on his laurels, and has maintained a steady career ever since. His appearance here is a rare and welcome treat. If that isn’t enough to lure you downtown, throw in another formidable guitar cult-hero, Nashvillian Phil Keaggy, whose run with late-’60s Ohio psychedelic rock band Glass Harp began a long career that has seen him become a prominent force in contemporary Christian music. (Nonbelievers, don’t let that scare you away. Bottom line — he’s just a badass guitar player.) Add to the mix Lambchop/Silver Jews/half-the-bands-in-Nashville guitarist William Tyler — a soon-to-be cult legend in his own right whose 2010 solo debut Behold the Spirit scored a whopping 8.6 from the notoriously picky Pitchfork — and you’ve got the makings of, well, a fully qualified revival. Can I get an Amen?
