Lana Del Rey was recently interviewed for L’Official:

I like “Coachella,” actually. I put it in the song exactly the way I was thinking about it driving home. I love when I can do that. And for me, it was such a culmination of things: Seeing Father John Misty, being with his wife; realizing there was a real problem with North Korea, that it was an impending, bigger world problem. It was to the point where I did not want to go home after the festival. I stopped at this crazy place called Rim of the World Highway in Lake Arrowhead [California]. I sat there, went to the redwood grove, and really had a moment with myself.
