Mr. Cartier makes fast and furious beats clearly indebted to the likes of electro-tech legends like Dopplereffekt, D.I.E., and DJ Godfather, but with a cheekier and harder British twist. BBC, Mixmag, and Resident Advisor have all taken a shine to “London’s illegal rave martian,” and his speedy beats have found a home with those who like their club trax alien, intergalactic and rough around the edges.
