When Soulfly frontman Max Cavalera was a teenager, he was recording his first albums with Sepultura, the Brazilian-based band – co-founded by Cavalera and his brother Igor – that eventually became one of the biggest metal bands of the ’90s.

Today, Cavalera, 43, is giving sons Igor, 17, and Zyon, 19, a crash course in life as a touring band. Along with their 25-year-old stepbrother Richie’s band Incite, Zyon and Igor’s band Lody Kong will open for Soulfly on the Maximum Cavalera Tour at Tremont Music Hall Sunday.

The teenagers aren’t new to the road. On her blog, their mother (Max Cavalera’s longtime manager and wife) Gloria Cavalera writes about how the toddlers (with Igor barely a year old) joined Sepultura on stage in the UK for what ended up being their father’s final show with the band.

“They were exposed to it from the beginning,” says Max Cavalera. “When they got into music, they got into metal. It’s exciting to have them in the house. We go to CD stores together, do our iPods together with our favorite songs, discover new bands together. They practice in the house. It’s a real metal house.”

Cavalera says stepson Richie has been singing with him since Cavalera’s 1995 cult side project Nailbomb. Both younger kids started out as drummers until Igor switched to guitar and vocals.

“From the beginning of the Soulfly tours, Zyon would sit behind (drummers) Roy (Mayorga) or Joe (Nunez). They’d give him tips,” he adds. More recently, the young drummer has tapped Uncle Igor (Septultura/Cavalera Conspiracy) for advice and is playing his uncle’s drums on tour. Cavalera says Zyon’s uncle told him: “They’re just sitting in the jam pad collecting dust. Put some mileage on them.”

“I’m glad he has his uncle, (because) I’m not a drummer at all,” says Cavalera, who showed his other son how to write riffs. “People talk to me after the show and say, ‘Your kids’ bands rock.’ Some people put me on the spot and say, ‘Aren’t you worried that they’re going to challenge you?’ ”

Cavalera adds that his rock n’ roll lifestyle has made it nearly impossible for the two boys to rebel.

“Most kids rebel ’cause their parents are too straight and don’t let them do anything,” he says. “We’re the opposite. They can’t rebel against us ’cause we’re crazier than them. They’ll lose.”

Cavalera is currently straight edge (“I did anything and grew tired of it”), but the prolific band leader hasn’t slowed down elsewhere.

He’s already working on a follow-up to Soulfly’s 2012 album “Enslaved” – an album produced by Terry Date (Soundgarden, Pantera) that he predicts will be out late this year. He’s toying with a “Hunger Games”-like futuristic concept for the record.

In September, he’ll record with an as-yet unnamed metal supergroup featuring Mastodon’s Troy Sanders, Dillinger Escape Plan vocalist Greg Puciato, and drummer Dave Elitch (formerly of the Mars Volta). Cavalera is also completing his biography, “A Boy From Brazil,” with British biographer Joel McIver.

He predicts it will be an inspirational story.

“It shows you can be from a place like Brazil – or most any place in the world – and make it in the music business,” he says. “It gives people hope.”
