It’s supposed to be -5 degrees Fahrenheit in Detroit tonight, which means it must be about -500 Celsius in Saskatoon, home of The Deep Dark Woods. (Actually, I picture Saskatchewan as being one big wheat field, with about ten trees scattered here and there, but what do I know, I’ve never been there.) Such cold is clearly irrelevant to this quartet, who offer up easy-going country rock more suited to the bronze glow of fall than the brutalities of winter. In fact, I’d go so far as saying these are warm songs, with steel guitar or, as in “All the Money I Had is Gone,” a fantastic old organ sound wrapping around you like an old blanket. Vocal harmonies smooth country grooves, lyrics of wistful longing — all perfect for curling up and staying under the covers, and due on Feb. 17.
