Kendrick Lamar

Back in late 2014, Kendrick Lamar debuted an untitled song on The Colbert Report that didn't end up on the great To Pimp A Butterfly, and last night (1/7) he debuted "untitled 2" on The Tonight Show Starring Jimmy Fallon. It's a funky, jazzy song that would've fit nicely on TPAB and it has Kendrick going offfffff at the end. It's too good to be ignored as some non-album throwaway, and going by his reaction after Kendrick finishes the song, Fallon probably agrees. Check it out, and watch clips of Fallon interviewing Kendrick, below.
