So much of pop music is auto-tuned, polished, shaved down until all the rough-hewn, distinctive elements are faded and gone. It’s tragic, really. But up and comer Luke Underhill frames his gravelly voice, unapologetically, with his first single “I’ll Be Waiting,” an amalgamation of Bryan Adams, John Mayer and Gavin DeGraw. It is unmistakably him, too, slyly gliding across throwback soft-rock, which deals in hearty singer-songwriter lyricism and anthemic-style production. In a brand new live performance video, premiering today, Underhill looks the crowd in the face and pours his heart out. The yearning of the lyrics to the tenderness of his phrasing, particularly on the verses, sets the tone for the intense and raw hook, hitting you squarely across the eyes. “I try and I try,” he wails, backed by brisk guitar lines and thudding percussion.
