Aussie Producer PhaseOne Teams Up With Erra For Another Electro-Metal Banger

PhaseOne makes us enjoy our favourite heavy bands even more than we already do. The dubstep-meets-metal producer is no stranger to collaborations: he has teamed up with Northlane, Excision, Silverstein, Modestep, Crystal Lake, Thy Art Is Murder and countless others.

Now, the DJ returns with World Unknown alongside progressive metal giants Erra. The song is the latest tune in a series of collaborations; it follows Icarus featuring Polaris, which has already racked up millions of streams. Watch the Icarus music video here.

"Compositionally, this is one of my favourite songs I've written," PhaseOne said about World Unknown. "It flows so seamlessly between the metal and electronic sections and all around is such a powerful and emotional track! 

"This was especially fun to write because Jesse from ERRA had a lot of hands-on work in the writing process, coming over to my studio to track some guitars and vocals. It felt like a REAL collab, compared to my usual process of writing everything and finding a vocalist."

Erra's Jesse Cash noted: "When I realized Graeme and I both lived in LA, I suggested meeting up in person to try and write something together from scratch. We were really excited by the idea of doing a true collaboration versus simply adding vocals to a pre-composed instrumental," he shared. 

"I met him at his studio and just messed around on guitar a bit before we landed on a riff that we could build a song out from. Graeme kind of blew my mind with his efficiency and speed in creating exciting electronic layers. It completely shaped the momentum of the song. 

"We accomplished what we hoped to, which was a song that properly incorporated both of our individual styles into a cohesive marriage. From that point, adding vocals was quick and natural. [Vocalist] JT [Cavey] and I basically ended up rolling with the first draft of the melodies and patterns you hear in the final version."

Erra recently opened for The Plot In You and put on a show punters would've been happy to call a headline performance. Tim Price wrote, "This could just have easily have been Erra's headline show tonight, as the production, sound and stage show was headliner-worthy. They rolled out Gungrave and unrelentingly assaulted The Triffid with Scorpion Hymn, Sol Absentia, Eye Of God and Divisionary - and the back half of the set was super mosh-heavy."
