With punk, pop and a little '70s rock boogie, San Antonio's Girl in a Coma forges a vibrant, hooky sound. They formed around the millennium when BFFs Jenn Alva and Phanie Diaz discovered that Phanie's little sister, Nina, could not only play guitar but also sing. Eight years their junior, she's the real deal—a fine player with a smoky croon, as comfortable with riot grrrl fire as breathy indie pop or even sultry crooning. These diverse impulses fuel their latest, Exits & All the Rest. It ranges from blustery garage rock and glam-punk to surf rock and indie pop. —Chris Parker
