Big Betrayal

Big Betrayal is a song performed by Deep Cut during Splatfests. It is one of four songs that will play during Splatfest battles, added into rotation during Drizzle Season 2023 for the Shiver vs. Frye vs. Big Man Splatfest.

Description
Big Betrayal is a midtempo EDM track with elements of house and Eurobeat. The first half of the track is in the key of A minor, opening with a lighter chord progression that revolves around the v and bVI (E minor and F major) with synth leads panned left and right that resemble sirens. This transitions into the section over which Shiver, Frye harass Big Man in the music video, with electric bass and synthesizers that share a unison bass line. When the sung vocals come in the song modulates to Bb minor, with Shiver and Frye singing hits along with the instrumental backing. The chorus comes in after a 1-bar break with the idols harmonizing with a vocoder to a punchy, syncopated melody and is followed by a halftime section similar to Till Depth Do Us Part that loops into the intro.

Big Betrayal features production techniques that aren't heard often in Deep Cut's vocal tracks, such as sample splicing and abrupt cuts in the backing track, which are more prominent in Return of the Mammalians tracks like Deep Cut's Theme and Surprise and Shine.
