ELECTRICITY! Sounds Like: A Janis Joplin-Aretha Franklin hybrid with a mic … but a Lucinda Williams-Bonnie Raitt hybrid with a pen For Fans of: Alabama Shakes, B.B. King, Mavis Staples Why You Should Pay Attention: After Potenza's spellbinding blind audition yielded a four-chair turn on NBC's The Voice, a visibly moved Pharrell Williams told her she was "giving this generation something they've never seen before." Potenza is to the blues what Adele is to pop: a colossal-voiced singer who merges her old-school influences with a modernistic sound. Her new album, Monster, solidifies endless Janis Joplin vocal comparisons but also colors between the lines of Memphis blues, Nashville Americana, New Orleans funk and L.A. punk. Its lyrics are personal and personally therapeutic, as she empowers herself through tunes denouncing industry naysayers and embracing her fuller-figured, boisterous self.
