A D.C.-based sextet, Sub-Radio has a signature sound that’s positive and uplifting––a brand of pop-rock whose well-put-together fusion of guitars and electronics gives a smiling nod to ‘80s pop music. Production is stellar, loaded with an array of clever effects (including panning synth-horns) that lend each track a certain fizz. All of it is spearheaded by singer Adam Bradley, whose tenor is ideal, even climbing to a falsetto when it’s called for. Meanwhile, the group’s vocals deliver a buoyancy that’s all-out infectious. We can see this band making an impact in a live, summery setting, lifting the crowd with songs like “What You Want to Hear” and the thumping “Disco” that seem tailor-made for a festival singalong.
