Pearl Jam is set to celebrate their 20th anniversary in grand fashion; not only are they putting on a weekend music festival with Queens of the Stone Age, The Strokes, and others, but they are releasing a documentary featuring rare footage and interviews with the band. We have your first look at the trailer for the Cameron Crowe directed rock doc.

Pearl Jam is one of those rarities in the history of American rock music, as friend of the band and Soundgarden vocalist Chris Cornell says in the following trailer, "American rock bands...they break up, and Pearl Jam managed to stay together". Pearl Jam is one of the few American rock bands who have maintained a high level of success and done so without ending the band, though there were a few close calls.

Fans will get a rare (and I do mean rare) glimpse inside the world of Pearl Jam in the upcoming full length documentary titled simply 'PJ20'. Longtime friend and collaborator of the band, Cameron Crowe ('Almost Famous', 'Jerry Maguire'), spent the better part of the last year milling through thousands of hours of unseen footage from the Pearl Jam  vaults. The result was the documentary that will see a one night only worldwide theatrical release on September 20th, it will also get a full run starting September 23rd in select key markets.

The film will take fans on a journey from the band's days under the moniker of Mookie Blaylock, all the way up to the recording of the new album (which will hopefully be out this year sometime). A few months back there was a very brief teaser posted online, now we have the full length official trailer for you. Enjoy.
