Glenn Tilbrook and Chris Difford have been working together since 1974, mixing New Wave attitude, blue-eyed soul, and power-pop finesse into sly, irresistible nuggets like "Out of Touch." But the two have taken plenty of artistic detours as well, whether dueting with Elvis Costello ("From a Whisper To a Scream"), taking on country (Difford's "Cowboys Are My Weakness"), or trying out R&B-informed pop (Tilbrook's "This Is Where You Ain't").
