 — he sings on a song called 'Lynch Mob' that we did together in the studio in L.A.; he flew to L.A. to do this collaboration. I was really proud because, to me, Roger is like the godfather of New York hardcore; Agnostic Front is one of the pioneer bands of the whole New York hardcore scene, so it was like recording with a legend of hardcore. The Cavalera album is really intense; that's all I can say about it. It makes the first album sound like pop music."

Regarding the songwriting and recording process for the new Cavalera Conspiracy album, Max said,

"I wrote a lot of the stuff and I sent it to Brazil to (Igor) in the form of a CD — like four tracks of the riffs — so that he would be familiarized with the songs by the time I got to the studio. And then I brought another CD with me, which was, like, newer songs I had just got done (writing) for the album. And everything else we did in the studio together — me and him there on the spot. I told him the idea of making a very intense album with some songs being only a minute and a half, so it's a cross (between) Minor Threat

 and Cavalera Conspiracy. So the idea was really cool — Igor really liked that — and from that point on, the album just grew and song after song, every day a new song came in. And I'm really happy with it. I think people are gonna be blown away when they hear it. I think it's a pretty cool album."
