Songwriter Chelsea Wolfe has made several fascinating transitions in her career and has a knack for blending genres as she crosses between them. But she’s been able to maintain a distinct artistic integrity, which makes each of her new projects especially exciting. She’s worked in atmospheric folk, rock/electropop/gothic hybrids, and now a blend of metal and electronica that gives unnerving and powerful voice to her recent struggles with sleep paralysis (a disorder in which reality and dreaming are indistinguishable). “Carrion Flowers” is as dark and bottomless as a river at night, a combination Lars calls “beautiful and terrifying.” Her album, Abyss, comes out August 7.
