We've been posting a lot about the upcoming Soulfly album 'Ritual' lately, and that's because the band have been firing off plenty of heavy material for our eager ears to listen to ahead of its October 19 release.

We already knew that Randy Blythe (Lamb of God) was going to be appearing as a guest somewhere on the record, and to our delight the band have released that very track. Titled 'Dead Behind The Eyes', the band seem to be channeling a bit of Lamb Of God themelves in a very metallic and thrashy five minutes. Randy lends his unholy vocals to the track at the very end in one of the heaviest endings we've heard for a while! Bang your head below:

In an interview with Rocksverige, Max Cavalera touched on how the collaboration with Randy came about:

"It was really cool. [Randy is] really tight with [producer] Josh [Wilbur] and Josh has done all the Lamb Of God stuff, and he was working on the Burn The Priest record, so I just told Josh to give him the tracks and, 'Show them to him, and if there's anything he likes, if he wants to sing on it, it's all cool.' I didn't have a song for him, so he showed him everything and what Josh told me was that they were listening to it, and the minute that song came on, it was nicknamed 'Bruiser Brothers', and the minute he heard it, it was, like, 'That's it! This is the one! I don't wanna hear anything else.' I had already written the lyrics, so I sent him all my lyrics and it was just good to have the Randy voice on it. He's got a real distinctive voice, really unique and that's what I like about guys like him. It's very original and you know it's him."
