Angel Olsen has made great strides between the homespun folk of 2012’s Half Way Home and the bold, noir-ish indie rock of 2016’s MY WOMAN, a journey documented on the rarities collection Phases. Ranging from compilation tracks (the moody “Fly on Your Wall”) to studio outtakes (the MY WOMAN–era “Special”), hushed (“May as Well”) to howling (the Roy Orbison garage rock of “Sweet Dreams”), the music here is a testament not just to Olsen’s range but her evolution as a songwriter, all anchored by her fluttering—but powerful—voice.
