Including an unreleased track.

Kendrick Lamar took the stage at the 58th annual Grammy Awards to perform ‘The Blacker the Berry’ and ‘Alright’, as well as previously unreleased material. It is powerful, arresting and one of the most ambitious showings the ceremony has ever seen. Earlier tonight, Kendrick won awards for Best Rap Song, Best Rap Performance, Best Rap/Sung Collaboration and Best Rap Album.
