Robert Randolph serenades Lawrence at Liberty Hall tonight

Blues and gospel — two of America’s most beloved art forms — are continually reinvigorated, thanks to fresh takes by innovative musical minds. The latest update arrives courtesy of Robert Randolph, who picks up where Stevie Ray Vaughan left off. Randolph’s riffs aren’t as incendiary as Vaughan’s, but his fluid playing and his smooth, burnished baritone are built for radio. Randolph developed a taste for roots rock as a pedal-steel player at the House of God in Newark, New Jersey.
