March 1987 double album after The Revolution split
Prince released Sign “☮” the Times in March 1987 on Paisley Park/Warner Bros. as a double album distilled from a flood of mid-80s sessions. Plans had run through the full-band Dream Factory with The Revolution, the pitched-voice Camille project, and the shelved triple set Crystal Ball. After The Revolution broke up, Prince cut the pile down to sixteen tracks that still jump genres inside single songs: funk, gospel, electro-pop, rock, and ballad writing. The title cut opens on a dry LinnDrum, sparse keys, and news-report lyrics about AIDS, drugs, and the bomb. It is apocalypse funk without orchestral padding.
U Got the Look (with Sheena Easton) and I Could Never Take the Place of Your Man kept radio hooks in the mix; The Cross and Adore leaned gospel and quiet-storm. If I Was Your Girlfriend kept the Camille vocal experiment in plain sight. Prince played most instruments himself in the Paisley Park/home-studio pipeline that defined his mid-80s work rate. The record sounds busy because the sessions were busy, not because a committee arranged “eclecticism.”
A one-man show, a tour de force, and a confirmation that pop’s former prodigy has come of age.
(Don McLeese, Chicago Sun Times, 1987)

Critically it became the consensus peak of his Warner years for many writers: the album that proved he could outpace the industry’s release calendar and still ship a coherent double LP. The tour filmed for the Sign o’ the Times concert movie locked the songs to a live band again. Later box sets and vault digs showed how much was left on the cutting-room floor, which only underlined the point of 1987: Prince’s inheritance here is a working method (write everything, then edit hard) and a double album that still gets cited whenever someone argues he was more than singles and movies. Funk historians point to the title track’s drum programming; pop radio still plays the hits; soul DJs still reach for Adore.
