It begins with her big, evocative voice. It’s devastatingly huge. (Pitchfork calls it: “Rough-edged and dark but still velvety, with fluid hints of gospel.”) And even when Cold Specks is showing restraint, you get the sense that her voice could blow the roof off wherever she’s standing, should she choose to do so. Fortunately, she doesn’t. Instead she focuses it on what she calls “doom soul,” a mix of Southern Gothic, traditional folk and American soul, which is slightly ironic as the singer-songwriter is actually Canadian and based out of London. But no matter, because with the release of I Predict a Graceful Expulsion (stream it below), she’s taken her talented act on the road. So do yourself a favor and see Cold Specks (above, doing “Lay Me Down” on Later … with Jools Holland) at tomorrow’s early show at Mercury Lounge. You’ll be glad you did.
