Blue Ridge-based singer Alexa Rose has the rare ability to find strikingly original melodies that sound like they must have existed for a long time, stored away maybe in the ether of creativity, self-evident and awaiting discovery. Moving deftly between complex dexterity and heart-tugging familiarity, Rose evokes the bright vocal experimentalism of Joni Mitchell and Joanna Newsom while maintaining the brassy attitude and simple refrains that run straight through American roots music from mountain ballads to rock ‘n’ roll.
