We've seen pictures of Kendrick Lamar in the studio with Pharrell before, but up until this point, any tracks that were recorded haven't been heard----until now. Kendrick took the stage to perform an unreleased The Neptunes-produced track titled "Staircases" with Buddy (who is featured on the song) and gave fans at SXSW a sneak peek. Check out the preview of the track above.
