Whether as a solo artist or as the lead singer for Grace Potter and the Nocturnals, this rambunctious Vermont vocalist effortlessly melds her blues-inspired rasp with oversized, attention-grabbing rock hooks. As demonstrated on her debut album, 2004's Original Soul, Potter is most effective exploring the darker side of romance—tales of revenge, anger and loneliness dot her rootsy pop songs. Yet the firebrand's powerhouse pipes always get the last word.
