Exuberant shining stars of the current indie folk rock crossover-into-mainstream-radio trend, The Lumineers hail from Denver, write infectious pop-hooky tunes with rustic log cabin charm, and set the big many-voice boy-girl choruses and strong lead vocals of frontman Wesley Schultz against vigorous percussion, clap-and-stomp-fueled rhythms, and stringed instrumentals given fine roots texture via mando and cello. Lumineers makes good use of nonsense words and sounds in their ballads, ala platinum-selling hit “Ho Hey,” though “Stubborn Love” is a more straightforwardly poignant ode. Both come off their 2012 eponymous debut, which peaked at No. 2 on the Billboard 200. Philly’s vintage-hued psych, folk, blues and garage-pop rockers Dr. Dog add even more value to this Saturday night bill. Also performing: Nathaniel Rateliff.
