Prince — The Black Album (1994)
One of the most iconic records of all time, ‘The Black Album’ was initially shelved because Prince had a bad feeling about it and he wasn’t happy with the fact that unlike his other records, it didn’t exude positive energy. The project was recalled, but not before some excited fans scooped up copies of it. Later, the album was re-released on CD, after the singer had a change of heart. Original vinyl copies fetch anywhere from $25 000 to $30 000 during online auction these days.
Caustic Window — Caustic Window (1996)
Richard D. James (also known as Aphex Twin) used an alias for a project called ‘Caustic Window’, but never could he have imagined that electronic music fans would be willing to drop thousands of dollars many years later just to hear what he had created. Although it was originally planned for wide release in 1996, only a few test pressings were produced before it was entirely scrapped. One of these copies showed up for sale in 2014, eventually finding a buyer through a crowdfunding campaign. The price? $46 300.
