At Lollapalooza 2013, Lana Del Rey showed just big an anthem her 'Great Gatsby' contribution was. She quite humbly introduced the track with plain facts: "Earlier this year I wrote a song for a movie ... it's called 'Young & Beautiful.'"

The crowd went absolutely wild, roaring with applause and cheers before singing along to every single word the beautiful chanteuse sang. Dressed like a hippie-hipster goddess in flowing red and a white headband, singing amidst her trademark Americana imagery, Del Rey's rendition was moving, vocally strong and lovely to behold -- and holy cow, was it loud!

Her performance of 'Body Electric' was similarly electrifying, if languid and lounge-y -- that's LDR's thing, after all. 'Ride' was similar in tone, and Del Rey remained relatively stationary in the center of the stage, clutching to her mic stand for the bulk of the song.

The lovely Lana closed her set with 'National Anthem,' garnering jeers only because she announced it was the last song and the crowd loved her so much that they literally begged her to stay. After seeing the drastic improvement in all of her performances, it's easy to see why they'd hate to see her go.
