Hall & Oates’ second album showed glints of the duo’s future as pop-soul craftsmen, but it also displayed their adeptness at tackling a wide array of song styles. The keening harmonies and pedal-steel guitars of “Had I Known You Better Then” reveal the pair’s knack for folk music, while the fragile falsetto at the heart of the fingerpicked “I'm Just a Kid (Don't Make Me Feel Like a Man)” illustrates their natural affinity for sighing soft rock.
