The creative process was marked by Smith's introspection. Feeling the imminence of turning thirty, he poured himself into composing songs that reflected this restlessness. In fact, the initial material he wrote took on a rather somber form, something he himself attributed to that feeling of aging. The band gathered, shared demos, and recorded a total of 32 songs at the home of drummer Boris Williams, of which 12 would make up the final album. Despite the seriousness of the lyrics and concept, those who were there remember that the atmosphere in the studio was not somber; rather, there were moments of laughter and camaraderie, even while recording tracks like Disintegration.
Disintegration became the group's most successful album to date, reaching third place on the UK charts and twelfth place on the US Billboard 200. It spawned highly recognized singles like Lovesong, which reached number two on the Billboard Hot 100, and others like Lullaby, Fascination Street, and Pictures of You. This album remains their best-selling record worldwide and is considered by many to be the culmination of the sonic explorations that The Cure had undertaken throughout the eighties.
