Metallica's Jason Newsted, former Faith No More frontman Mike Patton, and possibly Lemmy Kilmister from Motorhead and ex-Dead Kennedy singer Jello Biafra will be joining Sepultura onstage for a benefit concert on August 15 in Sao Paulo, Brazil at the Anhembi fairgrounds.The show marks the act's first public concert in the their home-country of Brazil with new singer Derrick Greene, who replaced Sepultura's founding member and vocalist Max Cavalera after he not-so-quietly left the group in January of 1997. The benefit will help provide relief to areas of the country where the crops have been destroyed due to severe weather conditions. It has been appropriately dubbed, "Noise AGAINST Hunger." A donation of at least 1 kilogram (2.2 pounds) of food will be collected at the gate along with a small ticket price. Also expected to be performing at the event are the Xavantes, the Indian tribe that appears on one of the group's earlier albums called, "Roots." As for the heavy metal outfit's current work, their upcoming album titled "Against" is due out on October 6 on Roadrunner Records. As previously reported by MTV News (see "Metallica's Newsted And Sepultura Find 'Hatred Inside'"), Newsted is featured playing both guitar and theremin on the track "Hatred Inside." The song was recorded in the bassist's home studio in San Francisco, back in May.
