Megadeth bassist Dave Ellefson and Anthrax counterpart Frank Bello announced that the debut album from their project Altitudes & Attitude would arrive on Jan. 18.

Titled Get It Out, the follow-up to their debut EP represents four years of work and is described as “a kind of rock ’n’ roll primal-scream therapy” in a statement. Guest artists include Ace Frehley, Gus G. of Ozzy Osbourne's band and Nita Strauss of Alice Cooper's group, among others.

A video for the album's lead track, “Out Here,” which features Anthrax guitarist Jon Donais, can be seen below.

“I've learned that writing songs is very cathartic," Bello said. "A lot of these lyrics are about the inner struggles of my life, and about the rage that has built up from my life experiences — my brother's murder, my father abandoning my family when we were young, leaving us with no funds to pay the bills. … The ups and downs of life in general. I've always had an anger inside that music really helps me deal with."

“The album has the perfect title," Ellefson added. “This is music that has been living inside of us for so long. There's a big musical part of each of us that doesn't get heard anywhere else."

He noted that the project “could only have happened at this moment in time,” now that he and Bello are able to look back on decades of experience. Noting that they are capable of working in an environment of “friendly rivalry,” he pointed out that it's a perfect moment for fans to see “other sides of us as artists — not just as musicians and performers, but as artists."
