Angel Olsen - is she legit? I believe she may be

Found her through youtube a few weeks back, and I keep going rewatching this concert about once a week. Her voice is great. Can't put my finger on who it reminds me of, but it's quite familiar in its uniqueness.

Anyone out there familiar with her work? It appears her first two records were different than what is in this show, and that her third record marked this change. What are your opinions? Is she worth delving deep into the catalog?
