He left the band over "artistic differences" in 2006 following brother and frontman Max's acrimonious departure in 1996. The current formation, consisting of vocalist Derrick Green, guitarist Andreas Kisser, bassist Paulo Pinto and drummer Eloy Casagrande have been working together since 2011.

But Igor hopes he and Max - who currently lead Cavalera Conspiracy - can work again with Kisser and Pinto. He tells Metal Wani: "I hope so. It's something that we don't know if it's going to happen or not. To be honest, I really hope one day we can do this in a very cool way."
