Florida Metalcore band Trivium introduce their fifth studio album In Waves with this minute and a half opener built off the bridge guitar riff from the middle of the title track. Frontman Matt Heafy explained to Alternative Press: "One day, [bassist] Paolo [Gregoletto] mentioned that I should record that bridge section, on a clean tone, onto a new blank track. At first, I didn't understand the purpose. But eventually, after layering some of the bridge parts, we added the chorus riff of 'In Waves' on top.The next thing that occurred was us layering tons of different guitars with different tones and tunings, all [of which were] playing the theme of the song. The 'war drums' were [created by using] drum sticks wrapped in napkins and duct tape beating down on flipped-over kick drums and toms. The snare and stick-click percussion was laid on top—[and] finally, the distorted, out-of-tune, real piano [was added] on top."
