BBC Radio 1's Big Weekend Festival had another star hit the stage after J. Cole, A$AP Rocky, and Rita Ora performed earlier.
Kendrick Lamar performed "Swimming Pools (Drank)" in front of the Derry/Londonderry audience. The crowd seemed to be pretty excited about the performance, especially the dude who decided to take off his The Chronic shirt. Check it all out above.
