Kendrick Lamar appeared on The Colbert Report as the show's last musical guest a couple weeks ago. After a hilarious interview with Stephen Colbert, he debuted an untitled track. The song features Thundercat on the bass, Bilal on vocals, and Terrace Martin on the saxophone. It has a real jazzy feel to it and Kendrick delivers some very passionate verses. This album is going to be special. Check out the interview and performance above and enjoy.
