GEMS’ sparkling and finely-tuned debut EP, ” Medusa” was one of the most promising releases of last year, so it’s nice to see that they’re still getting some push with a new video for “Sinking Stone,” which is probably the heaviest track on that release. The video, which is directed by BRTHR, captures the hazy desperation of the song well — slowed-down visuals depict two off-the-rails lovers as they joyride cop cars, do drugs, and play with guns. It all ends with a gruesome Bonnie & Clyde-esque standoff in the desert. It’s a haunting and atmospheric video, appropriate for this young and talented pairing.
