Kendrick Lamar's performance at the Sweetlife Festival in Maryland last night was turnt as you might expect, but the undisputed highlight of the night was an impromptu performance of "m.A.A.d. City" by a young female fan whom Kendrick invited on stage. 

After Kendrick made the dubious decision to give some random dude the opportunity to come up and rap, he brought up a young lady by the name of Ayanna to give it a shot. Backed by Kendrick's live band and with Kendrick acting as hype man, she got brought the crowd to its feet with a rendition of "m.A.A.d. City" both raucous and flawless.

In the words of Kendrick: "She killed that shit."

Skip to 5:20 below to hear Ayanna spit hot fire. Dylan would be proud. Also included below are last night's performances of "Alright" and "Bitch Don't Kill My Vibe."
