On their self-titled 1975 album, Hall & Oates proved themselves to be smooth soul-pop operators, scoring one of their most memorable hits with the smouldering, R&B-tinted “Sara Smile”. But the band showed their range as well, delivering hand-drum-laced groovers like “Alone Too Long” and synth-streaked character studies like “Gino (The Manager)”, adding up to an album that laid the groundwork for the duo’s world-dominating reign over pop music.
