Elvis Costello & The Imposters, “Look Now” (Concord)- Elvis Costello should be applauded for continuing to deliver his finely crafted brand of baroque chamber-pop at a time when most of his contemporaries from the late seventies have long since fallen by the wayside, and “Look Now” captures the bespectacled balladeer at something approaching the peak of his performing powers. The bulk of this excellent set was self-penned, although Elvis did join forces with peerless American tunesmiths Burt Bacharach and Carole King to create three of the album’s stand-out tracks, “Don’t Look Now, ” “Photographs Can Lie” and “Burnt Sugar Is So Bitter.”
