Legendary Brazilian thrashers Sepultura have been filming an official documentary for the past three years. To share their story with the world, Sepultura have launched a Kickstarter page to raise $100,000 in an effort to fund the upcoming film.

"Many of you probably don't know this, but we've been working the past three years on having a movie about the history of Sepultura," says vocalist Derrick Green in a new video clip. "It's something we're really passionate about and [have] been working on to put out, and I think with Kickstarter and what we're doing now is something we're really putting a lot in the hands of the fans and really having them be a part of something of the 30 years of Sepultura."

The film's official Kickstarter page offers more information on the Sepultura documentary:

Finally: The long awaited documentary about Sepultura’s incredible journey from Brazil to the world. Filmmaker Otavio Juliano has been following Sepultura for the better part of 2010-2013, a time of tension and triumph for the band, as they toured and recorded their album Kairos. Nothing has been off-limits. This amazing story will go through Sepultura’s history, myths, conflicts, personnel changes and struggles with the Internet economy in the early 2000s as well interviews and rare footage. This documentary is certain to bring fans closer to the band they love.

About 50% of the film has been shot so far. We have witnessed this historic band experiencing wrenching transformations and unprecedented growth. We opened Sepultura‘s vault and dig into the best rare and unseen footage of the last 30 years. We will see them at their most vulnerable and human, and also as idols of the heavy metal genre. Those elements make the overall film an uncommonly powerful statement.
