Kendrick Lamar made a surprise cameo last night at the Regent Theater in Los Angeles, where producer Adrian Younge was having a show in celebration of the launch of his new record label, Linear Labs.

According to OKplayer, the duo, plus soul singer-songwriter Bilal (who shows up a bit on Lamar’s recent album, To Pimp a Butterfly), ended up debuting a new song called “Money Over Love.” Watch three raging, piano-accompanied snippets from the show below, captured via Instagram.
