I read the NYT article and comments to the article about her last week. Then today she appeared on KCRW.com radio for a 1 hour interview/DJ set. Very impressive on both counts.

Her STAND FOR MYSELF album sounds pretty damn fine. Another Black Keys connection.
Extraordinary talent live as well. Saw her outdoors at Lincoln Center as opening act for a free David Crosby concert 2 summers ago. The crowd wasn't listening at first, the usual chatter during an outdoor opening act. After about 15 minutes, the audience was quiet and just listening.  By the end, she got a roaring standing ovation from the Crosby crowd. Dan produced her first album as well as the new one. A Jennifer Hudson voice singing folk inflected country. Unique.

Never heard of her.  Thanks for the post.  Need to go find her albums to stream...
