The Cavalera brothers are back. Max and Iggor Cavalera, who created some of the most influential metal records in music history with Sepultura and inspiring the heavy and extreme music scene over decades, are currently hard at work in the studio in Phoenix, Arizona, to record the fourth album of Cavalera Conspiracy.

Speaking to Australia's The Rockpit, Max stated, "It's a beast of a record. I think it's got a really cool mix of death and thrash metal. It's a really well-put-together album and we have Justin (Broadrick) from Godflesh singing on one song.

"I put it neck to neck with anything we did in the past — by far my favorite of all the Cavalera albums," he continued. "I think it's going to surprise a lot of people. I think we did a great job on the production. Igor's drums sound huge. The guitar sounds super crispy, super catchy and crunchy. Our friend Arthur Rizk, he produced the last Power Trip record and Inquisition album, so he's kind of an underground up-and-coming producer, he was really excited and motivated to work with us, and I really think he got some stuff out of me and Igor that wouldn't come out normally. He managed to get it out of us. That was great, so I'm very excited for people to hear it."

Set to be released in the fall of 2017 on Napalm Records, Max and Iggor have now left a message to their fans and the worldwide metal community with a first teaser and greetings from the studio. Check it out below.

Produced by longtime friend Arthur Rizk, the recordings of Cavalera Conspiracy's upcoming album will be documented by Horns Up Rocks, titled The Conspiracy Diaries. These exciting studio episodes will be released over the next months and will share an in-depth view behind the scene's of Cavalera Conspiracy's work in the studio.

The brothers Max and Iggor Cavalera formed the legendarily trailblazing heavy metal band Sepultura as teenagers together in 1984. Across six studio albums the Brazilian punishers perfected the art of darkness and extreme music with thrash classics such as Beneath the Remains Ariseand Chaos AD, while exploring the underbelly of third world political issues and broadening the genre's horizons with an exploration of indigenous culture, culminating with the landmark Roots album in 1996. A decade after Max left Sepultura and meanwhile released seven successfull records with Soulfly, the two brothers got back together in 2006 to form Cavalera Conspiracy: A bold testament to the talent and power these two possess together. An invigorating mixture of speed and aggression, finest thrash power and the fiercest riffage.

Get ready for one of the most heaviest and hotly anticipated metal records of 2017, as the Cavalera Conspiracy will strike back this fall.
