On July 1, Pearl Jam took to their Twitter with an enigmatic warning: “The countdown is on.”

The tweet referred to an ominous digital countdown clock on a section of the band’s website, and came with a Vine video of the countdown’s launch. The clock has been ticking for some time now, inspiring speculation regarding the release of a new single, a tour, or even the group’s next album.

And so today, exactly one week and two tweets later (“Are you ready?,” the band asked), the countdown is up – revealing the announcement for a mammoth, two-leg North American tour.

While Pearl Jam has continued to perform sporadically, the upcoming tour will see the band embarking on its first official tour circuit since 2010. Hints at a tour, and at new material, have been popping up for the last several months: All Access had at one point registered a new single, “Mind Your Manners,” for release on July 16 (only to quickly remove the listing), and guitarist Mike McCready even spoke with the Bob And Groz show in early May, albeit cryptically, about an upcoming record.

Finally, we’re beginning to get some answers. Just as the the countdown completed, the website launched a brand new clock timed at 3 days and 2 hours; in this light, the announcement of a tour all but confirms the arrival of a new album (or at least a new single), which will likely drop later this year. Only time will tell…
