Prince released 39 solo studio albums in his career -- and that may only be the tip of the iceberg.
In the days since Prince's April 21 death, new stories have emerged about little-known performances of the musical genius.
Now, rare footage has surfaced showing Prince performing with rapper Kendrick Lamar in 2014 at Prince’s Paisley Park estate to celebrate the release of Prince’s albums, "Plectrumelectrum" and "Art Official Age." Lamar, the Grammy-winning lyrical master, joined Prince on stage to perform "What’s My Name," from Prince’s 1998 album, "Crystal Ball."
The event was livestreamed at the time. But no archived footage was known to exist until the fan group, The Prince Museum, released video of the performance.
Lamar adds his artistic touch to the beginning of the song and then hands it off to Prince, backed by his band, 3RDEYEGIRL.
After Prince’s death, Lamar revealed that the two spent time in the recording studio prior to the release of Lamar’s epic album, "To Pimp A Butterfly." While the meeting didn’t produce any songs, Lamar said the experience was meaningful.
"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," Lamar told Grammy.com.
Lamar praised Prince as a "mysterious, mystique man," and said, "He took control of his music."
As the world tries to catch up with Prince's stunning artistic output, there's still the contents of his colossal vault, said to contain a mind-boggling trove of unreleased music.
