So far it's unofficial, but this could be the concert of the summer.

Pearl Jam's website accidentally revealed a handful of U.S. dates for a brief period before taking the info down, but not before Alternative Nation captured screen shots.

Here are the leaked dates:

Seattle Aug 8, 10 – Safeco Field
Missoula Aug 13 – Washington-Grizzly Stadium
Chicago Aug 18, 20 – Wrigley Field
Boston Sep 2, 4 – Fenway Park

Check out the screen shot below:

We'll keep you updated as more details are released!
