Lissie "Pursuit of Happiness" — Kid Cudi Cover
This cover might be the most enthusiastic, free-spirited one I've ever seen. Although Lissie clearly would've had to practice this, memorize the words, have her band learn the chords etc., it somehow still feels like it was just a totally spur of the moment decision. Not only that, but the fact that she tells the crowd she's going to take a shot before she performs it makes the moment that much more magical.
Things get even more meta if you listen to Schoolboy Q's latest album, Habits and Contradictions which samples Lissie's cover of this Kid Cudi song on "Hands on the Wheel" a track that also includes a feature from A$AP Rocky. Stream Lissie's blissed out Kid Cudi impression below.
