Tupac Shakur’s legendary discography could be about to gain an incredibly rare addition — but only if a serious collector is prepared to pay $250,000.

Momentsintime.com is offering a never-before-heard package featuring lyrics and previously unheard recordings of Tupac, all the way from late 1990 and early 1991 — before he signed with Death Row Records.

The content comes from an unreleased album that he recorded with a group named Jesse and the Kidz, which was shelved after one of its members died in a tragic accident.

Tupac sings lead on three of the songs, and while the lyrics have never officially been made available, there are a few sample sheets that are available to be previewed.

The sale is not public, but listening access without limitation is given to the buyer — actually releasing the music, however, would still need to be accompanied by the permission of Tupac’s estate, which holds rights.

So if you’re a hardcore hip-hop enthusiast with deep pockets, this could be a once-in-a-lifetime chance to own a part of hip-hop history.
