Next up on our 2012 Advent Calender: Hardrive boss and Hyperdub heat-bringer Terror Danjah.

At once one of grime’s most influential and most idiosyncratic figures, Danjah’s been commandeering grime’s lunatic fringe since since the turn of the millennium, heading the Aftershock collective and releasing a host of warped grime riddims over the last decade. This year has been a big one for him: his second Hyperdub LP Dark Crawler arrived this autumn.

FACT can now present a special version of Dark Crawler‘s titular interlude, which recurs numerous times over the course of the LP with cameos from the likes of Riko, Trim and Kozzie. This special version comes newly furnished with a scabrous vocal turn from Hyper, best known for his work in N.A.S.T.Y. Crew, and it’s a fantastically aggie reading. Click below to download.
