Cavalera explained to Altsounds.com
how the collaboration came about: "I was at the Deftones show in L.A., I was singing with the Deftones, it was a benefit for the bass player Chi that's in a coma. In the dressing room I saw Greg; I had met Greg on the Cavalera Conspiracy tour when they opened up for us in the US, so I said to him 'Hey man, how you doing? Do you live here?', and he said 'Yeah.' I said 'I'm in the studio doing some recording, would you like to do some screaming? Cos I'm doing a new Soulfly album and I think you'd be great on it.' Because I'm a fan. I think Dillinger Escape Plan is one of the greatest bands to come out in the last couple of years, very original; Greg's voice and lyrics are great. He was so excited about it that he sent a message to Gloria the night before we did it saying 'tell Max we are going to do something f--king epic'. So I was like 'cool, this guy's really excited', and he was, he came in the studio and heard 'Rise of the Fallen', and we started working on it; he put the first verse on it and right there the song took off huge. We did the chorus, and then he did the last part all on his own. When we listened back I was like 'this is a great song!'; it just turned out fantastic."
