1989’s Disintegration represents everything Robert Smith and his bandmates ever envisioned. Smith’s pop hooks and emotional outbursts are accompanied by deep electric-guitar washes and synths that are equal parts doomy and romantic. Though he was capable of writing succinct pop songs (“Lovesong”), Smith preferred to stretch out his explorations on love and obsession, particularly on the gorgeous “Pictures of You” and “The Same Deep Water as You.” His heartfelt longing overwhelms the lulling, hypnotic grooves for a career highlight.
