When Prince passed away on April 21, 2016 it not only left a giant purple hole in the hearts of music fans worldwide, it also launched a fascinating new mystery: What’s going to happen with Prince’s vault?

It’s been long known to Prince fans and music insiders that The Purple One maintained a massive, secretive vault containing copious amounts of unreleased music, movies, videos, and as we’re coming to learn, memorabilia, and items of personal significance.

In the absence of a formal will, Bremer Trust, the executors of Prince’s estate, had to drill into Prince’s vault so they could properly assess its content. Though Bremer has not made its findings public, lists containing some of the items in the vault have already been leaking to the media.

Though many of these items are already familiar to Prince devotees, there’s a fascinating array of previously unknown recordings and projects that span Prince’s career and interests.

Here’s list of what we know the vault contains, so far:
