In the post-rock outfit Red Sparowes, Emma Ruth Rundle wields her guitar like glacial force of nature. She’s explored other sounds in her projects Nocturnes and Marriages, and even with her textural, experimental releases as a solo artists. But her new solo album, Some Heavy Ocean, is something else entirely. On stunning songs like “Shadows Of My Name,” which is being debuted here, Rundle lends folky twang and her poignant voice to sprawling swells of blackened atmosphere and mood. In a sea of dark-folk contenders, “Shadows Of My Name” overflows.
