The Ronettes weren't the most commercially successful girl group, but their music was some of the most groundbreaking in the field, thanks to their association with the legendary Wall of Sound producer Phil Spector. Their biggest hit, "Be My Baby," is widely regarded as one of the crowning achievements of Spector's oeuvre, and of girl-group pop in general. In fact, many critics have deemed it one of the most supremely romantic records of the rock & roll era; Spector's production frames the song's yearning lyrics and Ronnie Bennett's sweetly sultry vocals in a sweeping, near-symphonic level of emotion. Even though the Ronettes never managed another hit as big as "Be My Baby," many of their subsequent singles boasted the same kind of creative synergy between Spector and Bennett. It apparently carried over into real life as well, since the two were married in 1968, not long after Bennett went solo. Unfortunately, the union was an unhappy one, as Spector soon turned reclusive and controlling, largely preventing her from recording (or even leaving the house). After their divorce, she recorded sporadically without much success, but became something of a female rock icon when she published her survivor's-tale autobiography.
