After teasing the new single on her site over the past few days, Lorde has released the full track, which is accompanied by a video directed by Joel Kefali and Lorde.

Lorde says of the new release, "This is a song I am very excited about, it’s so much fun to me. Obviously when making this album I did a deep-dive into 60s, Flower Child culture. I wanted to understand the commune life, dropping out from society and trying to start again. That really resonated to me when writing this album. One thing that occurred to me as a major parallel between that time and our time is our wellness culture and our culture of spirituality, pseudo-spirituality, wellness, pseudo-wellness. Things like eating a macro-biotic vegan diet or burning sage, keeping crystals, reading tarot cards or your horoscope. These were all things that they were dabbling in back then, and that me and my girlfriends are dabbling in today. I was like "I think there’s a pop song in here". So this is kind of my extremely satirical look at all of those vibes."

"Mood Ring" follows previous singles "Solar Power" and "Stoned at the Nail Salon".

Solar Power - produced by Jack Antonoff - will follow 2017's Melodrama, and is described by Lorde as an album about the "celebration of the natural world".

In June Lorde contributed backing vocals to Clairo's "Blouse" and "Reaper" tracks from her Sling album.
