VIDEO : Kendrick Lamar Debuts New Song in Controversial Grammy Performance

Kendrick Lamar brought a politically charged edge to the 2016 Grammy Awards, performing a medley of three tracks, including two from his acclaimed 2015 LP, To Pimp a Butterfly. The rapper is the event's most nominated artist with 11 total nominations. He delivered "The Blacker the Berry" as a prisoner who breaks through his chains, then "Alright" backed by a group of African drummers and dancers. He finished by debuting an explosive new song that ended with cathartic screaming. Earlier in the evening, Lamar won Best Rap Album, Best Rap Performance, Best Rap Song and Best Rap/Sung Collaboration.
