Swedish House Mafia are back to their mysterious ways as they've planted a countdown clock on their website's landing page.

Previous clues of the group's highly anticipated return include cryptic posters hung up in Stockholm, as well a digital billboard promoting Axwell & Ingrosso's "Dancing Alone" that briefly flashed Swedish House Mafia's iconic three dots.

The website does not share what will be revealed when the count turns zero, nor is there an option to subscribe to a list to find out any key information first. All three members -- Axwell, Sebastian Ingrosso and Steve Angello -- have teased the countdown on their Instagram Story in unison.

Stay tuned for what the countdown reveals.
