Details: On her 2014 album Burn Your Fire for No Witness, Angel Olsen sings with full-throated exultation, admonition, and bold, expressive melody. With the help of producer John Congleton, her music now crackles with a churning, rumbling low end and a brighter energy. Angel Olsen began singing as a young girl in St. Louis. Her self-released debut EP, Strange Cacti, belied both that early period of discovery and her Midwestern roots.
