Brazilian/American thrashers SEPULTURA will reunite with producer Ross Robinson (KORN, LIMP BIZKIT, SLIPKNOT) to record their next album, tentatively due before the end of the year via Nuclear Blast Records. The CD will be tracked in June at Robinson's studio in Venice, California and will be co-produced by Steve Evetts, who previously worked with SEPULTURA on the "Nation" (2001), "Revolusongs" (2002) and "Roorback" (2003) albums, in addition to having collaborated with Ross on a number of other projects in the past.In a brand new interview with the official web site of Jason Korolenko (author of the upcoming SEPULTURA biography "Relentless - The Book Of Sepultura"), SEPULTURA guitarist Andreas Kisser stated about the progress of the songwriting sessions for the band's next CD: "We have thirteen songs, I think two or three lyrics, and some ideas. There's still a lot to be done. We're going to work a lot on tour, especially on lyrics and vocal arrangements, but the songs are pretty much there. All the riffs and structures, drums… a lot to be done on bass, as well. But soon we get to Los Angeles with Ross. We're gonna have some days of pre-production, you know, playing the stuff with him and seeing his suggestions, and then start recording… We're going to spend six weeks there working with him and Steve Evetts, both producers of previous SEPULTURA albums, so it's awesome to work with them together for this one. We're going to do two extra songs that we'd like to use as bonus tracks. One from DEATH, 'Zombie Ritual', and another one from a Brazilian band, CHICO SCIENCE… We're gonna do something in Portuguese, singing together… Me and Derrick [Green, SEPULTURA frontman] are gonna try to [sing the song together]. It's hard for myself too, man. It's Portuguese, but Portuguese from the northeast of Brazil. It's a very different way of saying things, and it's poetry from the region there. It's gonna be a challenge, man. Since we did 'Policia' and RATOS DE PORÃO, you know, a long way… like, 'Chaos A.D.' days, we never really recorded anything from Brazil. So it will be good to do this time, especially with CHICO SCIENCE." Asked about sharing lead vocals with Derrick for the first time since 1998's "Against", Kisser said: "Yeah, we did that [on 'Against'] because we spent eight or nine months as a trio, writing most of the stuff for 'Against'. And I tried my voice in many songs, in many bits, full songs and stuff like that, just for the hell of it. The idea was to be a trio and try to keep going as a trio. It was a cool experience for myself to try to use the voice and try to do the old stuff like I did before, when Max [Cavalera, former SEPULTURA frontman] wasn't able to play some shows we played as a trio. But that's something totally different, to try to make your own style and create your own characteristic way. We used for 'Against' because of that period of time, and then Derrick took over more because he's much better, you know. He's very focused on the stuff. But I would like to use my voice somehow, sometimes. And this time will be cool because I really love that song, love CHICO SCIENCE, and it's great that we wanna try to do something together. And musically, it's gonna be great to have [Derrick's] accent trying to say the CHICO SCIENCE poetry." The reunion between SEPULTURA and Robinson was first suggested by Monte Conner, the former Roadrunner Records A&R chief who is now the head of Nuclear Blast Entertainment, a U.S. partnership with Nuclear Blast owner Markus Staiger. SEPULTURA's upcoming CD will mark the first time the band will have recorded an album outside Brazil since "Against". Robinson produced SEPULTURA's classic "Roots" album in 1995. Released in February 1996 by Roadrunner, it was the band's last studio album to feature founding member and vocalist Max Cavalera. "Roots" sold more than 2 million copies worldwide and was certified gold in the United States by the Recording Industry Association Of America (RIAA) for sales in excess of 500,000 units. SEPULTURA has spent most of the past two years on tour in support of its 12th studio album, and Nuclear Blast Records debut, "Kairos", which hit stores in July 2011.
