Rare footage of Kendrick Lamar and Prince performing together at his Paisley Park estate has been unearthed by a Facebook fan account. 

The incredible clip – which resurfaced yesterday on the Prince Museum page – shows the late icon holding an album release event in 2014. According to the post, he was celebrating both Art Official Age and Plectrum Electrum, and had invited fans and camera crews into his mysterious Minnesota compound for a special Yahoo webcast.

The uncovered footage from the event shows Prince being joined by Kendrick Lamar for a special performance of “What’s My Name”; a track from the legend’s 1998 Crystal Ball boxset. See the full performance below:

This wasn’t the only time that the pair were set to collaborate, either. According to Lamar, Prince was supposed to feature on the track “Complexion (A Zulu Love)” from last year’s To Pimp A Butterfly – but ended up having to cancel due to time constraints.

“Prince heard the record, loved the record and the concept of the record got us to talking,” the Compton rapper told Grammy.com. “We got to a point where we were just talking in the studio and the more time that passed we realized we weren’t recording anything. We just ran out of time, it’s as simple as that.”
