Review: By her usually prolific standards, it's been a long time between albums for Angel Olsen. "All Mirrors" is her first album for three years - an epic gap given that she used to average an LP a year in the early stage of her career. As usual, Olsen has redefined her sound once more, offering up impassioned songs that come backed by bold, wall of sound style production from John Congleton. There are many moments of stirring intensity, where swirling strings, eccentric electronics and low-slung indie-rock grooves join forces to create stunning and arresting musical works of art. The more contemplative moments often sound a little like "Mezzanine"-era Massive Attack or Portishead, though Olsen's voice and Congleton's production are always unique enough to make comparisons with those bands moot.
