It's been four years since Pearl Jam released an album, but that could all change soon. Or, at least that's what Pearl Jam fans are speculating after the band launched a countdown clock on its website, and it will strike zero at noon Monday, July 8.

It's all speculation at this point, but we're looking at a number of possibilities. Yes, it could be the formal announcement of the band's new album they have been working on for a while now. But, it also could just be the world debut of Pearl Jam's new single, "Mind Your Manners," which has been rumored to be released July 16.

Fans are hoping for the best of all worlds -- the single, a new album and a world tour. Pearl Jam is promising a "new PearlJam.com" on the countdown, so it's likely going to revolve around the new music, and hopefully, a tour. It's been 10 years since the full band has played a show in Texas other than Austin City Limits in 2009.

If you're anxious for a tour, you should become a Ten Club member sooner than later. Once the tour is announced, you likely won't have a shot at presale tickets if you're not already a Ten Club member.

Whatever it is, Pearl Jam is hiding it until the clock strikes zero. Head on over to Pearl Jam's website to see the countdown.
