Knife Party have teamed with Tom Morello for a genre-bending new collaboration, "Battle Sirens," which incorporates the EDM of the former duo with the Prophets of Rage and former Rage Against the Machine guitarist's blunt, funky riffing. The four-minute instrumental blends eerie-sounding guitar in the beginning with atmospheric synth sounds before giving way to a hard-rocking riff and, later, some unpredictable drops and electro sounds. Morello joined Knife Party onstage earlier this year at Ultra in March, where they debuted the tune.
"Tom hit us up when we were in the studio saying he'd always loved the idea of merging his guitar riffs into the electronic world and we bounced some ideas back and forth until we had the final version," Knife Party's two members tell Rolling Stone in a joint statement. "Performing this track live as a surprise during our Ultra set was insane."
"'Battle Sirens' is the cross genre hard guitar/hard EDM mashup I've been waiting to hear for years," Morello says. "The devastating grooves, monster drops and insane tension that are a hallmark of both Knife Party and Rage Against the Machine are elevated to a crazy level with this jam."
