Released at the height of Hall & Oates’ ‘80s peak, Big Bam Boom fully incorporated cutting-edge studio technology and urban dance music into the duo’s buoyant soul pop. Robotic voices stutter about on the opening track, “Dance On Your Knees,” before “Out of Touch” gradually gives way to the pair’s sweet vocal harmonies, surrounding them with big, clanging drumbeats. On “Some Things Are Better Left Unsaid,” processed guitars and stinging snares bandy around Daryl Hall’s impassioned pleas, finding a balance between the human and the programmed.
