Kendrick Lamar performed select songs from his To Pimp a Butterfly album in Washington D.C. with the National Symphony Orchestra last night. The show was the first stop of Kendrick's "Kunta Groove Sessions" tour, which is meant to be done in more of an intimate setting, and was really set off with the live band behind him. Kendrick performed "These Walls," "i," "Alright," and more, while the crowd was hanging on his every word from start to finish. Further details on Kendrick's ongoing tour can be found here.
