8. Prince Dream Factory
Planned Release Date: 1986
Reason It Was Shelved: Dream Factory would have been the first Prince and The Revolution albums to have had the entire band in the studio during production. By June of 1986, Dream Factory became a 19-track double album and after The Revolution ended later that year, tracks slated for the album were featured on Prince's Sign O' The Times project instead.
Why We'd Kill To Hear It: How can Prince and The Revolution make an album more epic than Purple Rain? Let's start by putting on twice as many tracks and inviting the whole band in the studio. It's unfortunate that the pieces never came together to finish the album, but carryover tracks like "Sign 'O' The Times" and "I Could Never Take the Place of Your Man" showed us we could've had another masterpiece on our hands.
