Tom Morello has shown his versatility on his Atlas Underground project, and recently he added to his resume lending some of his stylish guitar work to the new 5 Seconds of Summer song, "Teeth."

Luke Hemmings and Michael Clifford spoke to Zane Lowe's World Record about their new music, which saw them working with Ryan Tedder, Andrew Wyatt and Charlie Puth as well as Morello.

"We actually did have a fourth horseman," state the pair. "Tom Morello actually played on the track [Teeth] as well ... We're grateful enough to have him on the track and he plays the last outro. That’s a big feat for us as well. We were rehearsing we missed the opportunity to be there but we have recorded proof that it was him." Morello and the band's own Calum Hood both have feature moments on the track.

Of the song, Hemmings states, "We're in the studio with Andrew Watt, Nellie, Tim Posey, who we did Young Blood and a couple other…and we were writing for like a month or I mean a bit more than that and just trying to search for something that was a step forward from Young Blood and all that stuff that we're writing on the third album and Ryan Tedder was in this day and we're kind of flipping through. I always wanted to write with him for years. As a band we look up to One Republic obviously, and him as like a pop song writer so to write with him was already awesome. We're kind of flipping through ideas and kind of written a little bit and it didn't really work and then at the end of the day this idea came about and yeah, it happened really quickly. A lot of times the best songs just kind of fall out."

Clifford adds, "I think for us we've kind of felt that ‘Teeth' was always going to be the track that was kind of setting the like precedent for the rest of this record and I think easier for us has always felt like bit of a set up. Kind of easing into the new different styles and genres and visuals and stuff like that, and I think Teeth is where we're going to come balls blazing."
