Back in 2014, we reported that Skrillex was contributing his talents to the set of Transformers: Age of Extinction. Though a Skrillex track wasn’t fully featured in the film like Wreck It Ralph, you can bet his staple sound design is tucked neatly amongst the film’s roaring mechanoids and frenzied battles.
Below is a short film documenting the behind-the-scenes final touches of Transformers 4. While the entire 22 minutes is wildly entertaining, we’re mostly concerned with the segment beginning at 13:30, when Sonny Moore takes over composer Steve Jablonsky’s studio.
In the clip, you can see Skrillex stripping down his own tracks and building new ideas to offer an extensive library of otherworldly sounds for the film’s FX and score. We already realized Skrillex’s design insanity, but this segment gives us an entirely renewed appreciation for the scope of what he can create.
