Although she covers Tom Waits, the big news is that Krall is emerging as a fine songwriter. Where the glamour puss previously penned only several songs, here she co-writes six with influential husband Elvis Costello. Some, like “Abandoned Masquerade” and “I’ve Changed My Address,” are stark jazz ballads. But others put Krall in either Norah Jones territory (the catchy, pop-flavored “Narrow Daylight”) or the Joni Mitchell camp (the cool, confessional narrative of “Departure Bay”). Clearly, marriage suits her.
