Leah Siegel is from Brooklyn, but don’t hold that against her. While indie rock and pop music seem to bleed effortlessly from that distinguished borough these days, Siegel creates sounds that reside just outside the Brooklyn bubble. She’s a singer and instrumentalist, among other things (dancer, clothing designer), and her stellar band is made up of musicians who have played with Loudon Wainwright III, Sufjan Stevens, and others. There’s something a little outré about her music, and she’s capable of casting the kinds of spells that PJ Harvey and Cat Power are known for. In the hands of producer Geoff Stanfield (Sun Kil Moon, Moby), the hushed white space of “If You Don’t Want to Be Alone,” the seemingly carefree bounce of “Machete Gang Holiday,” and the bleak, torch-song feel of “My Left Eye” have a strange, dreamy quality that renders them something other than what they appear. “She’s a River” and “Our Hearts” hint at radio possibilities for Firehorse: their dark underbellies don’t quite override the cool, jazzy trip-hop vibe of the former or the melancholy, shadow-strewn pop of the latter.
