Like catching two decent shows for the price of none, Lincoln Center Out of Doors’ annual Roots of American Rock fest presents a historic confab of rock ’n’ roll elders alongside a pair of no-depression singleton stars. The Rockin’ Rockabilly Revue of septuagenarian ass-kickers includes impeccable Sun Records guitarist James Burton, larger-than-life Arkansas powerhouse Sleepy LaBeef, two-hit Beatles influence Charlie Gracie, groundbreaking Motown signee Johnny Powers, and Texas tornado Gene Summers. The remainder of the evening centers on recklessness and redemption: British pub rock, punk, and new wave linchpin Nick Lowe is a brilliant smoothie who cloaks nuanced menace in classic country warmth. And former Drive-By Trucker Jason Isbell’s new Southeastern reflects the difficult and often dark aftermath of life-or-death rehab.
