Gary Clark Jr. as electric blues whippersnapper Sonny Blake was the best thing about John Sayles’s otherwise oversweetened slice of Southern cinematic sociomythology, Honeydripper. But it has taken another four years for the 27-year-old Austinite to really come into his own with a scorching set at last summer’s Crossroads Blues Festival in Chicago and the August release of a tight, promising teaser of an EP, Bright Lights. “You’re gonna know my name,” promises Clark in the alcohol-soaked title track before launching into a solo of Hendrixian intensity on his Epiphone Casino guitar. He’s just as comfortable with North Mississippi Hill Country stomps and Delta laments. Everyone gets a breather when Clark unfurls the occasional R&B slow jam, so take the opportunity to snag a cold one at this sure-to-be-packed showcase for the finest recent incarnation of a fading species.
