If you're one of the many who remember the day you first bought Pearl Jam's debut album, 'Ten,' and then listened to it until the cassette melted into your stereo, then get ready to feel old. Yup, it's been a full 20 years since 'Ten' came out and established Pearl Jam as one of the defining voices of the grunge era, and not only have they been kicking ass ever since, but apparently they've been filming their musical journey all along.

With an upcoming tour on the horizon to celebrate their 20th anniversary as band, we now have our hands on the first trailer and exclusive poster for the upcoming rockumentary, 'Pearl Jam Twenty.' As per the studio:
'Pearl Jam Twenty' chronicles the years leading up to the band's formation, the chaos that ensued soon-after their rise to megastardom, their step back from center stage, and the creation of a trusted circle that would surround them -- giving way to a work culture that would sustain them. Told in big themes and bold colors with blistering sound, the film is carved from over 1,200 hours of rarely-seen and never-before seen footage spanning the band's career. 'Pearl Jam Twenty' is the definitive portrait of Pearl Jam: part concert film, part intimate insider-hang, part testimonial to the power of music and uncompromising artists."
Check out the trailer and the poster:



They're definitely going for the 'U2 3D' effect with the poster, but who cares -- this will be awesome and it's sure to have one hell of a soundtrack.

Directed by Cameron Crowe, it's set to hit theaters on Sept. 20 for one night only before getting a week-long run on Sept. 23, and it features the many members of Pearl Jam (obviously) along with appearances from Soundgarden's Chris Cornell and the late, great Layne Staley from Alice in Chains. We don't know about you, but we're already dusting off our ripped jeans and plaid flannel for this one.

How excited are you for 'Pearl Jam 20?'
