An American singer-songwriter, Angel Olsen has a very distinctive style. She sometimes sounds like a chanteuse from the ’40s, and other times like a modern indie rocker. Her newest album, Burn Your Fire For No Witness, was released in February, and was the successor to her 2012 debut, Half Way Home. She will be playing on May 13 at the Music Hall Of Williamsburg in Brooklyn and on May 14 at Johnny Brenda’s in Philadelphia.
