At the heart of most success stories lies a framework of brand invention, the creation of a persona or x-factor that raises an artist above the noise. But for pop vocal group Anthem Lights, it’s reinvention that’s catapulted the talented foursome to over 147 million YouTube views and 1.4 million monthly listeners on streaming services. The indie group’s success is due in large part to the foursome’s vocal prowess (Caleb Grimm, Chad Graham, Spencer Kane and Joey Stamperareall exceptional singers),creativemash-ups and reinventions of pop hits and beloved hymns.
