In 1996, British big beat pioneers released their savage dance hit “Firestarter,” now being doused with the raw power that is Death Grips. The rap-rock duo’s ferocious stylings are already well suited to the track, which only benefits from Death Grips’ twisted, noisy remix. Still, every time I hear any version of “Firestarter,” I can’t help but think of a well-oiled Justin Theroux hanging upside down (or something like that) in Charlie’s Angels 2. Maybe it’s a generational thing.
