This post is about "Bravado", a song about someone who is withdrawn, doesn't want to be, and breaks out of her shell. Kind of seems to me like Lorde might be talking about herself. I personally love how this song starts out quiet and builds huge with her confidence.
I'd like to remind all of you that this was released in 2013 and recorded in 2012. She turned 16 in 2012. She was barely 16 when she recorded this, and obviously already had it written. And yet, the maturity in both music and lyic are amazing.
(Edit: 13 Nov 2020) The official video disappeared, so here's a fan-made one featuring scenes from the movie Moonlight.
When Lorde went to Live on Letterman, she didn't forget this song, even if it didn't make her album. Her live performance built up just as much as the song does on record.
