This is one of two bonus tracks on which Soulfly frontman Max Cavalera
's sons play drums. Max's first boy Zyon Cavalera contributes to a cover of Sepultura's "Refuse/Resist
" and his younger brother Igor Cavalera plays on this number. Max told Altsounds.com
it was an important experience for him to share with his two sons. He added: "It was kinda fun too, In a punk rock way, to involve my kids in the process, because they are drummers as well and they play in the house all day long, I listen to them play and they think they are ready to record because they sound really good, they bang the drums all day long. So I let them pick their own cover song: Zion picked 'Refuse/Resist', which I think fits him really well because his heartbeat opened the original Sepultura Chaos AD
album, that's his heartbeat on the beginning; Iggor picked 'Excell', kind of like a thrash punk skate Venice band from the 80s, so that was fun having them in the studio."
