The first sound Leonard Cohen makes on his new album is a nanosecond's rush of labored air. It's not a wheeze, exactly, or a hiccup. But it's not a singer's note, either. The singing (such as it is) soon follows, and the 82-year-old's somber tone signals that matters of grave import are about to be discussed. He's making an inquiry into the peculiar strain of creeping soul distress, both personal and universal, that he's been diagnosing since at least 1992's The Future.
