Kendrick Lamar's performance yesterday was one of the more talked about moments from this year's Pitchfork Music Festival, mostly because Lady Gaga showed up to watch his set. But Kendrick's live show was buzzworthy too, especially with the addition of his new single "Swimming Pools (Drank)." In the video above, watch as he spits his new drinking anthem, and gets the crowd to join in on the chorus. Kendrick's upcoming album good kidm.A.A.d city is due out October 2.
