Imagine Dragons is up to something, and it involves a 15-minute silent video.
The clip, titled "1:," features the silhouettes of two people standing beneath some cliffs, under a starry sky. While there's no audio in the video, which officially clocks in at 15 minutes and 19 seconds, the image changes slightly throughout -- for example, the stars change patterns and comets fly through the sky.
As for what the video is teasing -- if anything -- people are guessing a live album or a deluxe version of Evolve could be in the works. Fans looking for clues point to the "1:" title and reason that the video's 15:19 length could refer to a possible release date of January 15, 2019. That's a Tuesday, however, and albums are released on Fridays.
