Last year, it was reported that rock-friendly director Cameron Crowe (Almost Famous, Singles, Vanilla Sky) was helming a doc about the band, which would coincide with the 20th anniversary of their groundbreaking 1991 debut album, Ten.

We now know the film's called Pearl Jam Twenty, and it'll be out sometime in September. An exact release date hasn't been determined, but there has been chatter in the webiverse suggesting the band might organize some kind of festival around Labour Day.

Crowe, meanwhile, recently told Rolling Stone that making the documentary was tough since he was given 18 to 20 hours of footage and told to put some kind of story together.

"Pearl Jam Twenty is, 'How do we do The Kids Are Alright of Pearl Jam, and sonic blast the best stuff?"

Keeners will recall that Crowe's directed Pearl Jam’s 2009 video for Backspacer's "The Fixer." He's also been busy with an Elton John/Leon Russell documentary, The Union, which he's been making at the same time as Pearl Jam Twenty.

IMDb doesn’t list a release date for the Elton doc; the Pearl Jam film is listed in post-production.  Pearl Jam was also honoured for its environmental activism last Friday, which was Earth Day.

Looks to be a stellar anniversary for the Eddie Vedder and the gang. (Apologies for the old vid clip but all the good stuff has been disabled).
