At the time of its release in 1987, Sign ‘o’ the Times was a double LP collection that reinstated Prince’s musical supremacy, and it remains among his finest achievements, sprawling and inclusive in its ambitions, stylistically diverse and deeply moving throughout. From the quiet, resigned tones of the opening title track where AIDS, crack and nuclear bombs suggest the end of times to the immediate party for the apocalypse that follows with “Play in the Sunshine,” Sign shows every facet of Prince’s stunning creativity. Like most successful double albums, over time favorites change and new surprises reveal themselves. However, there’s an immutable brilliance to the sexually ambiguous “If I Was Your Girlfriend,” an admirable symmetry to the sprite and energetic keyboard pop of “I Could Never Take the Place of Your Man” and an ageless soulfulness to “Adore” and “Slow Love” that provide the deep thoughts while “Housequake” and “It’s Gonna Be A Beautiful Night” take care of the dancefloor.
